Collimated Deep-UV LED LBLED-0285, 285 nm
LBLED-0285Design Tools
The LBLED-0285 is a collimated deep-UV LED with a center wavelength of 285 nm (FWHM 15 nm), delivering up to 55 mW of collimated optical power from a 25.4 mm output aperture with a beam divergence of <10°. It is driven by the LBLED-CT6V controller (sold separately) and connects to standard SM1-threaded lens tubes, filter holders and irises.
LBTEK's Collimated LED provides 29 wavelength range: options within 255 nm-1300 nm, including two color temperature collimated white light LEDs at 4000K and 6500K, meeting the needs of different wavelengths from ultraviolet to near-infrared. It contains collimating Optical Components, enabling the output beam divergence of the collimated LED to be less than 10°, with white light divergence angle <7°. The light exit has an SM1 internal thread, which can be connected to other standard SM1 threaded devices. When used with the controller LBLED-CT4V/LBLED-CT6V, the light intensity can be adjusted directly through the knob on the controller, and external trigger and Software control are also supported.
Note: Light Sources controller needs to be purchased separately.
