    • 820–860 nm OCT Spectrometer

    The 820-860 nm OCT spectrometer is a high-axial-depth, high-throughput OEM spectral detection module designed for SD-OCT (Spectral-Domain Optical Coherence Tomography) systems. Featuring a 40 nm spectral bandwidth and a 2048-pixel line-scan camera, it delivers a maximum measurement depth of 9.0 mm (in air) and an axial resolution of 9.2 μm (in air). The module incorporates a high-efficiency transmission grating and a stable optomechanical structure, offers USB3 or CameraLink interfaces, and supports multiple high-speed acquisition rates, making it suitable for integration into industrial, medical, and OEM OCT systems.

    Product features：820–860 nm OCT‑dedicated wavelength band；0.02 nm high spectral resolution；High‑speed acquisition；High optical throughput

    Part Number：MP‑OCT‑820‑860

    Application area：Industrial OCT inspection | Medical OCT imaging | 3D / Volume OCT | Internal structure inspection of transparent and semi‑transparent materials
