With 300 lines per millimeter groove density and optimized blaze angles (24.8° \/ 31.6°), this transmission grating delivers reliable diffraction performance across the 780–2500nm spectral range. The anti-reflection coating maximizes transmission efficiency, making it ideal for low-light-level detection, portable spectrometers, and instrument OEM integration.\u003c\/p\u003e\n\u003cp style=\"font-size: 16px;
