The VRC1 and VRC4 are credit-card-sized viewing cards; each has a photosensitive region that allows for the easy location of an IR, VIS, or UV 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. Since the active region does not require charging, the emission is persistent even when used in CW applications in a darkened room. 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. In addition, when the card is used in a darkened room with a sufficiently bright source, the fluorescence from the activated photosensitive region can be seen through the back of the card or the photosensitive region can be activated by illuminating the back of the card. This is especially useful for aligning the overlap of two beams.

The VRC2 is similar to the VRC4 and VRC1 except that it requires the user to charge the card with light from a visible light source. Also, 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 VRC5 is a smaller card measuring 2.4" x 1.79" (61.87 mm x 45.5 mm) and is designed for the 700 to 1400 nm wavelength range ; this card also requires room light charging. The photosensitive area meaures 1.5" x 0.75" (38.1 mm x 19 mm) and is encapsulated between two layers of durable clear plastic.
