Laser Viewing Cards

The VRC2 is a credit-card-sized viewing card with a photosensitive
region that allows for the easy location of a IR light beam and its focal
point. The card is made from a durable plastic with a photosensitive
region adhered to the front surface of the card. The active region
requires the user to charge the card with light from a visible light source,
and the emissions from the card are not persistent and require the user
to move the card around for optimal brightness of the beam spot.The detection region extends all the way to
the edge of the card in order to facilitate the use of the card during alignment procedures.
