Optical path length: 25.4 mm (1 inch) Optical path width: 16 mm Outer dimensions: 29.5 x 20 x 40 mm Material: Quartz glass Key benefits Precise and repeatable light path length for reliable measurements and alignment in optical systems. Compact form factor that fits easily into crowded benchtops, housings, or small instruments. Quartz glass construction provides a durable, stable component suitable for precision optical work. Simple, straightforward integration with standard optical setups without requiring special adapters. Applications and use scenarios Laser alignment on a laboratory optical bench where a defined 25.4 mm light path is required for calibration and setup. Compact spectroscopy or absorption experiments that benefit from a defined optical path in a small instrument footprint. Imaging or microscopy configurations where a precise, compact optical path component is needed to maintain alignment and performance.
