Photodetectors

QUBIG offers a selection of Free-Space Amplified Photodetectors that are sensitive to light in the UV to the SWIR wavelength range. The amplified photodetectors have a built-in low-noise transimpedance amplifier that provides a fixed-gain for exceptional low S/N ratios.

QUBIG's photodetectors are matched with our QDR-ADU free-space modulator driver which was designed for all common laser frequency stabilisation techniques like PDH and FM/MT spectroscopy.
