This eyepiece with an integrated pointer is designed for educational use and group demonstrations. The built-in pointer makes it easy to accurately draw attention to a specific structure or feature within the specimen, helping viewers follow explanations more clearly during teaching or collaborative research. The eyepiece is installed in place of a standard 10× eyepiece. In binocular or trinocular microscopes, a matching eyepiece without a pointer should be installed in the second eyepiece tube to ensure comfortable observation.

This darkfield condenser is designed to enable darkfield microscopy, a technique used to visualize unstained, translucent specimens that absorb little light and are often invisible under standard bright-field illumination. To use the darkfield condenser correctly, it must be paired with an objective whose numerical aperture is lower than that of the condenser. With a numerical aperture range of 1.26 to 1.30, the condenser is suitable for use with 20× and higher-magnification objectives.

This darkfield condenser is designed to enable darkfield microscopy, a technique used to observe unstained, translucent specimens that absorb very little light and are often invisible under conventional bright-field illumination. For proper operation, the numerical aperture of the condenser must be higher than that of the objective. With a numerical aperture range of 0.7 to 0.9, the condenser is suitable for use with dry objectives providing magnifications from 4× to 40× and numerical apertures below 0.9.

This polarizer and analyzer set is designed to enable polarized light microscopy. The set includes a polarizer and an analyzer that work together to create polarized illumination for advanced specimen observation. The polarizer is mounted on the collector, while the analyzer is installed in the slot of the microscope stand above the revolving nosepiece. The polarizer is fully rotatable through 360 degrees, allowing precise control of the polarization angle. The intensity of transmitted light varies depending on the relative orientation of the polarizer and analyzer.

The differential interference contrast (DIC) device is designed for studying transparent, low-contrast specimens that are difficult or impossible to observe using standard bright-field microscopy. This technique enhances image resolution and clarity through optical methods rather than chemical staining, while also providing additional structural information about the specimen. The DIC method creates a pseudo-relief effect, giving the image an apparent three-dimensional appearance. 

This transmitted light spectroscope is a simple yet precise instrument designed for observing and analyzing the spectra of various light sources. It features a tube with a precision entrance slit and a 600 lines-per-millimetre grating, allowing users to easily point it at different light sources such as the sky (to observe the solar spectrum and Fraunhofer absorption lines), flames for chemical analysis, liquids for their absorption spectra, or the bright lines from discharge tubes and lamps.

This compact spectroscope features a high-performance flat-field concave grating in a module measuring just 136 x 120 x 75 mm and weighing 1.2 kg. It includes a built-in Lodestar X2 guide camera and an argon-neon calibration lamp for precise wavelength calibration. Both the input and output are equipped with T2 threads, making the unit compatible with most imaging cameras that use T2 thread connections. Starlight Xpress recommends pairing this spectroscope with the Trius SX-694 camera for optimal performance.
