Delta Optical ProteOne Microscope (SKU: DO-3800)

Biological Microscope for Medical and Veterinary Laboratories

This biological microscope is designed for medical and veterinary laboratories as a reliable instrument for routine observations. It features semi-planachromatic optics that provide clear and accurate imaging suitable for everyday laboratory work.

The trinocular head is secured in a way that prevents removal without tools, ensuring stability and safety during operation. A wide 20 mm field of view allows comfortable observation, while the upper stage position lock helps protect both the specimen and the optics.

The microscope is built on a solid, stable stand and includes a dedicated compartment for convenient power cord storage.

Precision Mechanics and User Protection

The device is equipped with a mechanical stage featuring a vernier scale, which improves the precision of specimen positioning. Coaxial coarse and fine focus knobs allow smooth and accurate adjustments.

A practical locking lever makes it possible to secure the upper stage position once sharp focus has been achieved. After lowering the stage to replace a specimen, it can be quickly returned to the same focal plane. This mechanism also reduces the risk of damaging slides through accidental use of the coarse focus adjustment.

LED Illumination and Expandability

Long-life LED illumination provides bright, cool white light without generating excessive heat inside the microscope. This ensures comfortable long-term operation and protects sensitive specimens.

The microscope can be expanded with additional observation techniques, including phase contrast, dark field, polarization and LED epifluorescence, offering greater versatility for advanced laboratory applications.
