Outstanding Image Flatness Plan Achromat Objectives

The CX23 features plan achromat objectives that preserve outstanding image flatness throughout the field of view.

Uniform LED Illumination with Reduced Blue Color






The LED light source provides long life time of 20,000 hours, and offers low power consumption. Also, its reduced blue color preserves vivid colors on HE staining.

A Torque Release Function Prevents Damage

Damage when excessive force is applied to the coarse focus or stage knob is prevented with a built-in torque release function.
