Balanced photodetector for THz spectroscopy

Balanced photodetector with low-noise design using a dropper-type power supply.

The "Balanced Photodetector for THz Spectroscopy" is a one-package balanced photodetector that incorporates optical elements suitable for electro-optical detection in THz spectroscopy. It includes a λ/4 wave plate with a rotating polarizer holder to add optical phase bias to the probe light that has passed through a nonlinear optical crystal, and a Wollaston prism that separates the light into two orthogonal polarization components. Additionally, the position of the Wollaston prism is semi-fixed and adjustable, allowing it to accommodate subtle wavelength changes. 【Features】 ■ No need for external optical components as it incorporates a λ/4 wave plate and Wollaston prism (can also accommodate configurations without internal optical components) ■ Selectable between two wavelengths: 800 nm and 1.56 μm ■ Fixed transimpedance gain: 80 dB *For more details, please download the PDF or feel free to contact us.
