Even though described as “linear” sensors, many members of these back-thinned CCD families are 2D arrays of pixels, with 1024 or 2048 pixels in the horizontal (spectral) direction and with up to 500 pixels in the vertical (imaging) direction.

Please note that the DC-IRSPG Infrared to Visible detection card uses a storage type phosphor.  The phosphor must be charged with light before use.  Any light can be used though a fluorescent or UV light will work best.  The DC-IRSPG can detect lower power IR sources, but the phosphor loses its charge quickly when illuminated with IR.  Therefore, you should move the card around when detecting the IR source so that the IR beam hits freshly, charged phosphor. The DC-IRSPG can detect a much wider range of infrared beams, 700nm to 1500nm, than the DC-IRUCG, but the DC-IRSPG must be charged before use and once the phosphor is hit with an IR beam, it glows green for a few seconds before losing its charge.

CCD sensors are the candidates of choice for applications and experiments that require high sensitivity and low noise in order to deliver best SNR and limit of detection. Broadband spectroscopy applications, such Optical Emission Spectroscopy, and UV-VIS Fluorescence measurements benefit from the high QE of back-thinned CCDs, while Raman instrumentation at 785nm and above, is best configured with the NIR-enhanced version of these same sensors.

tec5USA’s electronics can operate these 2D sensors in two modes: Spectral mode, where vertical pixels in a column are all shifted down and summed in the serial register prior to readout, effectively using the sensor as a linear detector; and Image mode, where the sensor is readout one row at a time, or by a given number of regions of interest, effectively constructing an image of the focal plane.

Spectral and Image modes both have their applications: Single-channel, high-speed, high frame rate spectroscopy for Spectral mode; and multi-channel / multi-input sequential and/or simultaneous spectroscopy for Image mode.

These heavy duty clear detection cards are great for detecting a wide variety of light sources, aligning laser systems and testing equipment.  The phosphors used are incapsulated inside a 35 millimeter thick card protecting the phosphors from getting damaged from wear.  The cards are quite durable unlike the common paper cards.  Our unique transparent card with a translucent phosphor target, allows you to see behind the card when working with difficult tasks such as aligning a laser device.

Available in front-illuminated, UV-VIS back-thinned and NIR-enhanced back-thinned versions, CCD sensors are offered in a wide variety of formats, both in terms of length, height, full well, packaging and cooling options (such as uncooled, thermally-stabilized or cooled).

The DC-IRUCG uses a non-decaying, up-conversion phosphor that does not need to be charged.  However, the DC-IRUCG will work best for higher power IR sources.  Most remote controls can be detected with the DC-IRUCG because the LED's are typically 940nm and they are pulsed at high levels.
