Description
CamIR Adapter is a cost-effective Telecom C-band NIR image converter by DataRay Inc., the industry leader is design and manufacture of laser beam profilers.
Technology: A proprietary phosphor converts 1480-1605 nm photons to Silicon CMOS/ CCD detectable wavelengths image to the attached CMOS/CCD camera at a demagnification of x0.29 (PMF=3.5), to give an effective active area of 22 x 16.5 mm with a ½\", 1/1.8\", ⅔\", or 1\" cameras. The effective pixel size is 3.5 x the actual pixel size, but due to the phosphor, the primary limitation is the phosphors point spread function of ~70 μm FWHM, and ~200 μm at 1/e2.
The response to incoming irradiance is logarithmic. This is automatically corrected in WinCamD software, by setting the gamma in setup to 2.00. Like any phosphor, the response is spatially non-uniform. Typical beam diameter measurement accuracy is around 5 to 10%.
Performance and Pricing: This technology is better than the low resolution and image lag of IR vidicons, yet less sensitive and less uniform than InGaAs arrays.
