Optics

The epi-fluorescence attachment enables the use of the fluorescence technique, which relies on the ability of certain substances to emit light when excited by light of a specific wavelength. Some specimens display natural autofluorescence, while others require treatment with fluorochromes to produce a fluorescent signal. The attachment is installed in the optical path between the microscope stand and the head. Inside the unit is a five-position rotating turret containing four fluorescence filters with different wavelength ranges: broad-band blue (B), green (G), ultraviolet (UV), and narrow-band red (R).

This objective is designed for brightfield microscopy. The MAGUS Bio V360 microscope kit includes phase objectives, which contain a metal film ring etched onto the inner lens. This ring is required for phase-contrast observations, as it introduces a quarter-wavelength phase shift relative to the remaining light and reduces overall light transmission. For this reason, objectives without phase plates are recommended for standard brightfield observations.

This professional holder set is designed to securely fix labware of various shapes when working with an inverted microscope. It ensures stable positioning of dishes and provides convenience during sample replacement. The set includes four holders intended for culture bottles and similar labware. Each holder features two seating sizes, allowing compatibility with two standard labware dimensions. The holders are installed directly into the microscope stage according to the shape and size of the accessory being used.

Episcopic illumination provides bright, uniform, and shadow-free lighting of the field of view without causing heat damage to the specimen. It is specifically used for illuminating opaque objects in stereomicroscopy. The attachment is installed between the microscope head and the zoom objective. The light source is housed in a dedicated lamphouse, which is connected to the attachment by a flexible dual light guide. Light is delivered through the guide into the attachment and then directed to the sample through the objective. 

The MAGUS CLI18T illuminator is designed to illuminate samples with oblique light, making it possible to clearly visualize surface relief, scratches, cracks, and other defects through pronounced highlights and shadows. The design of the illuminator prevents sample heating and eliminates the risk of thermal damage. The light source is housed in a dedicated lamphouse. Light is directed to the specimen through a flexible dual light guide. The position of the light guide can be adjusted to set the desired illumination angle, allowing precise control over light and shadow formation for detailed examination. 

This LED ring light with a matte diffuser is designed to provide bright, uniform, and shadow-free reflected illumination. It is mounted directly onto the CMO stereomicroscope objective, allowing the light to be delivered coaxially. This illumination method is particularly important when observing flat, glossy, or low-contrast samples. The matte diffuser effectively removes harsh shadows and significantly reduces glare, producing soft and evenly distributed light. The LEDs require no warm-up time, reaching the selected brightness instantly and maintaining a stable color temperature even during extended use.

To generate a three-dimensional image, a CMO stereomicroscope uses a common main objective positioned strictly perpendicular to the specimen plane. Light transmitted through or reflected from the sample enters this main objective and is then divided into two parallel optical paths. The stereoscopic angle is 11 degrees. The separated light beams are directed to the eyepieces or to a digital camera. Changing the main objective alters the microscope’s overall magnification, field of view, and working distance.

To create a three-dimensional image, an Abbe stereomicroscope uses a common main objective positioned precisely perpendicular to the specimen plane. Light transmitted through or reflected from the sample enters the main objective and is divided into two parallel optical paths. The stereoscopic angle is 11 degrees. The separated light beams are then directed to the eyepieces or to a digital camera. Replacing the main objective changes the microscope’s overall magnification, field of view, and working distance.

The CMO (Common Main Objective) system allows additional accessories to be integrated into the optical path. A two-port beamsplitter is installed between the microscope head and the zoom objective, enabling the simultaneous use of two digital cameras. A stereomicroscope with a CMO design produces high-quality digital images without field distortion. This makes it an excellent choice for photo and video recording, as well as for presentations and lectures that rely on visual materials.

A beamsplitter with a single port is mounted between the microscope head and the zoom objective and is used for installing a digital camera. A stereomicroscope built with a CMO design produces high-quality digital images without field distortion. This makes it well suited for photo and video recording, as well as for presentations and lectures that rely on visual demonstrations.

This polarizer and analyzer set is designed to enable polarized light techniques. It includes a polarizer and an analyzer, and the intensity of transmitted light varies depending on their relative orientation. When the polarizer and analyzer are positioned perpendicular to each other, complete light extinction occurs. Polarized light is used to study anisotropic samples such as geological specimens, biological structures, and polymer materials.

The stage is mounted in the base of the stereomicroscope and is used for precise and smooth movement of the sample beneath the objective, as well as for documenting observations with a camera. Coaxial control knobs allow controlled movement of the specimen along the X axis (right and left) and the Y axis (forward and backward). The transparent glass surface of the stage enables work with both reflected and transmitted light. A vernier scale is provided for precise measurement along a single axis.

The MAGUS HCM360 system is a complete set designed for Hoffman modulation contrast microscopy. It includes plan achromatic objectives, a dedicated condenser, and a slider. The objective modulator is aligned with the slider’s slit apertures using a centering telescope supplied with the microscope. Hoffman modulation contrast produces high-resolution, relief-like images of living specimens. It enhances visibility and contrast while preserving fine structural detail and avoiding diffraction halos. This makes it suitable for long working distances and high numerical apertures.

The focusing mechanism is a structural component of the stereomicroscope designed to secure the microscope head to the stand. It enables precise vertical movement of the microscope head, allowing accurate focusing on the specimen. Focus adjustment is performed using coaxial knobs, which provide smooth and controlled operation during observation.

The MAGUS SPH2 phase contrast system includes a set of phase contrast sliders, a set of phase contrast objectives, and a centering telescope. This system is designed for the observation of transparent, low-contrast specimens that are difficult or impossible to see using brightfield illumination. Because staining procedures can damage or kill living cells, phase contrast offers a key advantage by allowing the study of living, unstained organisms in their natural state. The technique is widely used in medicine, ecology, pharmacology, agriculture, and related fields.

The epi-fluorescence attachment is designed to enable fluorescence microscopy. This technique relies on the ability of certain substances to emit light when excited by illumination at a specific wavelength. Some specimens naturally exhibit autofluorescence, while others require treatment with fluorochromes to produce a fluorescent signal. The attachment is installed in the optical path between the microscope head and the stand. Inside the unit is a four-position rotating turret that holds three broadband fluorescence filter sets for blue (B), green (G), and ultraviolet (UV) excitation.

The plan semi-apochromatic fluorescent objective is designed for both transmitted-light and fluorescence microscopy. The objective lenses are manufactured from fluorite, a highly transparent mineral that performs consistently across a wide wavelength range. Fluorite does not exhibit autofluorescence or birefringence and provides correction of the secondary spectrum. A high numerical aperture increases resolving power, producing images in the eyepieces and through a digital camera that are brighter, cleaner, and higher in contrast than those obtained with standard plan achromatic objectives.
