Main features
 
1. Excellent imaging performance: using toroidal mirror to correct astigmatism; Reduce coma and other phase differences through asymmetric optical path design and grating in-axis scanning design; The focusing mirror is larger than the collimating mirror, so that there is no dark angle in the whole flat field (no luminous flux loss at the edge of the focal plane).
 
2. Eliminating secondary diffraction light: The asymmetric optical path design optimized by computer simulation can accurately optimize the position of optical components, thus achieving the purpose of eliminating secondary diffraction light.
 
3. In-axis scanning technology of grating: It can keep the signal light on the surface of the center of grating all the time, greatly improve the splitting efficiency and accuracy of grating, and ensure high luminous flux and spectral stability.
 
4. Flexible & Easy to use: The selectivity of the entrance and exit of the spectrometer, various types of gratings, a full range of accessories and related software enable customers to customize the iHR spectrometer to meet any experimental requirements.
 
5. Excellent stability: It provides a long-term stable platform for spectral measurement. Adopt high-quality materials and integrated casting structure. The drive part is tested and rechecked to ensure that the system meets our repeatability and accuracy requirements.
 
6. Perfect combination with CCD detector: With the excellent quality of spectrometer and the manufacturing technology of CCD detector, the design of CCD and spectrometer is optimized. It has a full range of large and small CCD chips that can be matched with spectrometers. The detector has open electric, back illumination, deep depletion and normal incidence detectors, all of which have TE refrigeration or liquid nitrogen refrigeration functions.
