Other Products
By combining photodiodes with current amplifiers, we have developed a new series of high-performance photodetectors. The LCA-S-400K is available with either Si or InGaAs photodiodes, covering spectral ranges of 400 to 1100 nm and 900 to 1700 nm, respectively.
Key Features
Si PIN and InGaAs PIN photodiodes with wavelength ranges from 400 to 1700 nm; DC bandwidth up to 400 kHz;
Maximum conversion gain of 10⁷ V/W;
Minimum NEP of 75 fW/√Hz.
