Request InfoSpectrum Scientific Inc. (SSI)SPIE Photonics West 2022 Booth: 3321Spectrum Scientific’s (SSI) hollow retroreflectors are manufactured from solid aluminum, making them insensitive to vibration and positioning. Our replication process allows for high-volume repeatable performance down to <2 arcsec return beam accuracy. Mounting features and fiducials can be incorporated directly into the retroreflector allowing for easy alignment, additional design freedom, and cost reduction benefits.See full productRelated content from Photonics MediaPRODUCTSPromoted Content January 2023 IssueHigh-Speed Polarization ModulationThe PEM200 has a digital controller with USB 2.0 and Ethernet communication and optical enclosures with sleek, compact designs.
