Lot of 10 pcs Chromium-coated optical flat. Chrome-on-Glass (COG) Φ14mm
Note: Direct orders via email benefit from specialized technical support and bulk pricing for larger quantities.
Product Description
Professional Chrome-on-Glass (COG) substrates, essential for high-precision photolithography, mask making, and chemical etching processes.
Each substrate features a uniform, high-density chromium layer deposited via Electron Beam Evaporation (PVD) on an optical flat glass surface. These plates offer excellent adhesion and high contrast, making them ideal for:
- Production of optical masks and reticles
- Micro-patterning and thin-film research
- Calibration targets for microscopy
- Thermal and chemical resistance testing
