InGaAs avalanche photodiode balanced photodetector BAPD-200M-A

The avalanche photodiode (APD) balanced detection module integrates a low-noise APD detector, low-noise broadband transimpedance amplifier, ultra-low-noise isolated power supply, high-voltage power supply, and APD temperature compensation. The isolated power supply ensures that the output signal is not affected by external power sources. The APD temperature compensation improves the stability of the detection module. The avalanche photodetector features high gain, high sensitivity, high bandwidth, and low noise, making it suitable for applications that require precise and stable optical signal detection.

Isotope Rubidium 85 Reference pool (Diameter 22.68mm Length 71.2mm)

These flame-sealed cells contain a small amount of solid, >98% chemically pure, isotopically pure rubidium 85 (85Rb) under vacuum. The concentration of rubidium in the gas phase can be controlled by heating the cell or cooling the tip stem. Operating temperatures are typically 20-80°C. Rubidium has intermittent strong absorption lines that are used to calibrate tunable lasers and wavelength meters in the range of 6540-48300 cm-1 (207-1529nm). They can also be used to stabilize laser frequencies by locking onto a single strong absorption line. The quartz cell body is cylindrical; 22.68mm outer diameter; 71.2mm length. The tip stem is centered on the cell and protrudes no more than 10mm beyond the cell body. The window is angled 11° from normal and has a 2° internal wedge to prevent back reflections and etalon effec

1650 nm 45° Faraday rotato

Idealphotonics’ Faraday rotator is a device that achieves precise non-reciprocal rotation of laser polarization. It provides non-reciprocal rotation while maintaining the linear polarization of the beam. In conjunction with a polarizer, it can block the return light in the optical path . Device for precise nonreciprocal rotation of laser polarization Faraday rotators provide non-reciprocal rotation while maintaining the linear polarization of the light beam. When light passes through the Faraday rotator in a certain direction, the polarization state will rotate 45 °; when the light beam passes through the Faraday rotator in the opposite direction, the polarization state will rotate another 45 ° in the same direction relative to the magnetic field . Based on this principle, in combination with a polarizer, the return light in the optical path can be blocked. The Faraday rotator provided by our company is made of magneto-optical crystal with high Verdet constant and low absorption coefficient, which is highly reliable. M2 degradation is small. Combined with high damage threshold technology, the maximum product’s average power can reach 500W, with a wavelength range of 355 nm-4500nm.
