Description
Discover the cutting-edge innovation of fused silica transmission grating technology with Ibsen Photonics' high-resolution, high-efficiency gratings, designed specifically for compact spectrometers. The FSTG-UVVIS1250-702 grating, with its 1250 lines per millimeter, is optimized for the 190 – 850 nm wavelength range, providing exceptional performance in the UV, VIS, and NIR regions. This product exemplifies Ibsen's commitment to excellence, leveraging their leadership in holography and advanced wafer-based Holostepper™ processing to offer gratings that rival the performance of traditional reflection gratings at a competitive cost.
At the heart of each Ibsen grating is a holographic masterpiece, crafted from fused silica. Unlike replicated gratings, these are original creations, ensuring superior quality and precision. The unique transmission configuration of these gratings allows for a flexible and tolerant design, offering high diffraction efficiency and low polarization dependence across a broad spectral range. This makes them an ideal choice for applications that demand low noise and high resolution.
The FSTG-UVVIS1250-702 gratings are engineered to withstand challenging environmental conditions, with unbeatable temperature tolerance and low thermal expansion. This robustness, combined with low stray light and minimal wavefront distortion, ensures reliable performance in a variety of settings. With a grating area of 4 mm x 4 mm and a chip size of 5 mm x 8 mm, these gratings are compact yet powerful, making them perfect for integration into modern spectroscopic instruments.
