Hamamatsu Corp. has released linear image sensors that integrate CMOS-charged amplifiers and InGaAs photodiode arrays with wide dynamic range in a single housing. The G8052-256D has a 256-channel pixel array with 50-µm pitch, and the G8053-512D has a pixel array of 512 channels with 25-µm pitch. The sensors feature ceramic packages that eliminate the need for cooling elements. Specifications include active areas of 12.8 × 0.5 mm, peak sensitivity of 0.9 A/W at 1.55 µm and maximum photoresponse of ±5%. The sensors measure 31.8 × 15.1 × 3.2 mm and can be used as optical detection devices in DWDM monitors with gratings.
