Request InfoTerahertz Technologies Inc.Terahertz Technologies’ C-995 phase-locked-loop optical chopper achieves crystal-controlled chopping rates from 4 Hz to 5 kHz using only one blade. The use of Direct Digital Synthesis permits the rate to be set to a precision of 0.001 Hz. Frequency settings may be made via front panel controls or the bidirectional RS-232 port, or the chopper can be phase-locked to a user-supplied external clock. Both enclosed and open-style chopper heads are available.See full productRelated content from Photonics MediaPRODUCTSVision Spectra Autumn 2023 IssueSWIR LensThe Ophir® SWIR and NIR 25-250 mm f/5.5 (NFOV) f/4.0 wide-field-of-view continuous zoom lens from MKS Instruments Inc. is a compact, rugged device for 5- and 10-µm SXGA and 15-µm VGA...Promoted Content May 2022 IssueTracePro 2022Lambda Research Corporation is proud to announce the release of TracePro 2022, the latest release of our award winning TracePro software.
