Request InfoGigahertz-Optik Inc.Gigahertz-Optik Inc. has unveiled the X1-1 handheld multispectral-band optometer, which operates while showing multiple measurements made by the proprietary XD-450X three-cell detector series. Each reading is displayed on one line of the meter’s four-line high-contrast LCD. Remote-controllable, it features autoranging as well as manual range selection, and the user can select dose mode and integration time. It is compatible with single- and multisensor (up to four) light detector heads.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2022 IssueLaser Power MeterThe LabMax Touch Pro laser power meter from Coherent Inc. makes data acquisition and analysis for nW continuous wave lasers up to multi-kW, pulsed industrial lasers easy to access through an...Photonics Spectra February 2023 IssueEndoscopic Image SensorThe OH02B image sensor from OmniVision Technologies Inc. is a square, 2-MP, 1500 × 1500 resolution CMOS image sensor for medical use.
