MSM Photo Detectors UltraFast

UltraFast 20/35 SM

UltraFast 20/35 FS

The standard configuration of the Ul­traFast 20/35 SM photo detector

The UltraFast 20/35 FS free space photo detector with a focussing optics to prevent overfilling

The UltraFast MSM photo detectors have a bandwidth up to 35 GHz and can measure signals with wavelengths from below 400 nm up to 1.6 µm. The detectors are optimized for minimal pulse tail and oscillation-free impulse response.  These excellent features are ob­tained by exploiting the inherent advantages of the MSM (metal-semiconductor-metal) detector configuration such as low capacitance, low series resistance and large active area. Special structures and dopants enhance the responsivity and lower the electrical noise. The MSM detectors are an ideal choice for precisely characterizing the time and frequency response of high-speed optical sources and light wave systems.

Two Versions of MSM Photo Detectors are available:

UltraFast-20 (Bandwidth DC – 20 GHz)

UltraFast-35 (Bandwidth DC – 35 GHz
