Technical Description

 

The backlight LED light source is a high-brightness, stable and uniform light source with a flatter illumination field than conventional point sources. It comes with 2 frosted diffusers, mounted through the central SM1 threaded hole with an integrated diffuse reflection window, which effectively eliminates light concentration and further optimizes illumination uniformity.

This series covers center wavelengths from 454 nm to 640 nm and offers a broadband white light option.

The LED housing is equipped with 4 through holes compatible with Ø6 mm cage posts, enabling installation in 30 mm cage systems and DIY microscopy imaging modules for flexible configuration. Secure the cage post with the set screw on the side of the through hole using a 2.0 mm hex wrench.

In addition, the light source housing features four M6 countersunk slots, allowing the light source to be mounted to an optical table with cap screws, providing more options and convenience for system integration.

The LEDOTB controller is a compact controller for adjusting the light intensity of LED light sources. It can drive LEDs at a maximum current of 1000–2000 mA. Users can perform stepless dimming by operating a single potentiometer knob with integrated on/off function. This controller supports constant current drive mode (CW) and pulse mode (PULSE, via SMA 5 V TTL signal input). LEDOTB provides stable and reliable light source support for CCD camera exposure assistance and digital microscopy imaging systems.
