The Cassegrain-type all-reflective microscope objective is a optical component designed for high-precision imaging and multi-wavelength analysis. Featuring a 15× broadband reflective design with a 200 mm focal length and an infinite back focal distance, it supports confocal imaging across a wide spectral range from 200 nm to 14 µm. With excellent control of wavefront aberrations, the system achieves a combined RMS wavefront error better than λ/15, delivering superior image quality and spectral fidelity.
