Thorlabs VIS/IR Detector Card 400 - 640 nm 800 - 1700 nm VRC2
The VRC2 is a credit-card-sized detector card for viewing light in the 400 to 640 nm or the 800 to 1700 nm wavelength range. The lower front surface of this durable plastic card is photosensitive, made from a slow-fading phosphor, and enables the easy location of visible or near-infrared (NIR) light beams and focal points. Before using the card, it is necessary to charge the active region with visible light. As a consequence of the card needing to be charged to generate emission, during operation the user must move the position of the incident light spot around the active region to maintain the intensity of the excited emission.
To facilitate the use of the card during alignment procedures, the detection region extends all the way to the edge of the card and includes two engraved reticles for use in laser beam collimation. These reticles, formed from lines that are 0.004" (0.1 mm) wide, feature two concentric circles that have diameters of 0.06" (1.5 mm) and 0.28" (7.2 mm), as well as horizontal and vertical lines that are 0.51" (13.0 mm) long.
