Princeton Opto reveals 808nm high power VCSEL Illuminator
The new model, based on gallium arsenide technology, is suited to high speed photography
Princeton Optronics has announced the availability of 808nm high power illuminator model (PR-HPIL-800-W808) with power output of 800W using multiple Vertical Cavity Surface Emitting Laser (VCSEL) arrays.
Higher illumination levels are required for high speed photography as with increase of frame rate (or reduction of frame time), the number of available photons per pixel per frame decrease proportionately. Very high level of illumination is required to image certain fast events such as speeding bullets or blast fragments through the air. VCSEL arrays are preferred illumination devices for such applications because of their low speckle and flattop beam profile.
In the PR-HPIL-800-W808, four VCSEL array chips are mounted in the module and connected in series so that they deliver a power level of 800W from the module. We also supply the power supply which is triggered by the camera for some applications. A diffuser is optionally attached to the VCSEL arrays to increase the beam divergence, if needed. Also offered are illumination modules of various power levels starting from several watts to 800Watts for CW, QCW or pulsed illumination.
In addition to 808nm, Princeton Optronics offers illumination modules at other wavelengths such as 830nm, 976nm, 1064nm and at 680nm (red). The firm is a manufacturer of high power single and multi-mode VCSELs and VCSEL arrays, and has a diverse line of products suitable for many applications including illumination, sensing, and solid state laser pumping.
Below are two pictures of the product from two angles.
