SSP- 4 Infrared Photometry

What is the SSP-4?


SSP - 4 Infrared Photometer on a 12" LX200 GPS Telescope

After nearly 20 years and several attempts, Optec has developed a new Near-IR photometer for medium to large size telescopes. Relatively new InGaAs PIN photodiodes designed for the fiber optics communication market have reached very high performance levels compared to the IR detectors of earlier times. It is now possible to design and build an IR photometer, which allows a great many stars to be observed accurately in the J (1250nm) and H (1650nm) photometric bands. Using custom J-band and H-band filters the SSP- 4 allows amateur astronomers with 10-inch and larger telescopes to perform a level of scientific measurement unheard of just a few years ago.
