High-Precision, High-Quality
- Surface accuracy of λ/6 has been achieved by a newly-developed latest replicating technology (conventional Shimadzu product:λ/2).
- Stable quality due to premium quality master mirrors.
- Proven mass-production technology secures steady supply of large quantities.
Off-axis parabolic mirror
This aspherical mirror, which focuses parallel light to the focus point without aberrations, or converts a point light source from the focuse point into parallel light without aberrations, is used in spectroscopic systems that require high resolution.
