Request InfoTerahertz Technologies Inc.The C-995 microprocessor-controlled optical chopper produced by Terahertz Technologies Inc. provides chopping rates from 4 Hz to 5 kHz using direct digital synthesis. The compact system can be controlled from the front panel, which has a five-digit LED readout. A bidirectional RS-232 port enables users to remotely set the chopping rate to a resolution of 0.001 Hz and to read the status of the instrument. The device's phase-locked loop enables it to be synchronized to a user-supplied external clock, and the enclosed chopping head provides a wide range of chopping frequencies using only one...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2024 IssuePoint Source LEDsMarktech Optoelectronics’ line of point source LEDs has expanded to include high sharpness green LEDs and additional red LEDs for reflex sights, riflescopes, sports optics, camera viewfinders,...Photonics Spectra November 2023 IssueGoniophotometerThe LM-79 Moving Detector Goniophotometer (Mirror Type C) from Lisun Electronics is an automatic light distribution intensity 3D curve testing system for measuring LEDs, plant lighting, indoor and...Photonics.com 12/5/2022Black IR LEDsThe 940-nm OSLON® Black IR LEDs from ams OSRAM AG match automotive cameras’ field of view for driver and cabin monitoring.
