CASTECH's acousto-optic modulators (AOM) control laser intensity outside the cavity via digital or analog RF drive, with a frequency range up to 300 MHz and rise/fall times as fast as 6 ns. Design is optimized to your modulation speed, wavelength, power, beam diameter, and extinction ratio requirements, suiting laser marking, photolithography, medical procedures, and material processing.

The FPM-300S Series is engineered for reliable, sunlight-readable operation in outdoor environments, where strong sunlight and surface reflections can make screens difficult to read. Its 1800-nit high-brightness display maintains clear visibility even under direct sunlight, while an anti-glare coating reduces reflections to improve readability. An anti-UV coating helps protect the displa...

FEMTO has 2 new photoreceivers: HCA-S-20M-SI-FST - 20 MHz, Gain 1 x 10^5, wavelength range 320 - 1060 nm HCA-S-20M-BSI-FST: 20 MHz, Gain 1 x 10^5, Wavelength range 200 - 1160 nm

CASTECH custom acousto-optic modulators (AOMs) provide high-speed optical modulation, flexible configuration, and precision engineering for laser systems, photonics, scientific research, and advanced optical applications.

HS-2F-012 is a 2-channel single-mode fiber optic slip ring , designed for continuous 360° unlimited rotation optical signal transmission. Both rotor and stator ends are fitted with LC duplex metal fiber adapters with PC end face. Standard 150mm Ø2.0mm pigtails are pre-installed at factory. It can be quickly matched with LC couplers. Customers can customize external patch cords.

The NEW OE-200-BPR expands the OE-200 Series options by adding the balanced optical inputs option. The OE-200-BPR is available with Si and InGaAs photodiodes. The OE-200-BPR Balanced Photoreceivers feature low-noise kHz range and high gain.

Designed for fiber laser and sensing systems, CASTECH Fiber-Coupled AOMs deliver up to 300 MHz modulation, 6 ns rise time, and high extinction ratios for precise optical control.

All types of networks need verification of network performance and functionality, whether relying on traditional
