Apochromatic Refractors
We can offer you a range of very high quality refractors in this category. These include e.g. our two- and three-lens APM Apo instruments, our astrograph series, available as APM or APM-LZOS models. Equipped with Riccardi reducers / correctors or as a high-end version CNC LW II with Feathertouch extracts. All around excellent instruments that should leave no wishes.
Apochromatic refractor AP 130/780 LZOS 3.7-ZTA OTA
- Our LZOS Super ED 3-lens models come with a test report, meaning that each lens is individually measured using a Twymann interferometer and recorded with the serial number of the lens.
- Maximum Strehl ratio (as with the Zeiss APQ) is guaranteed to be 95% or better.
- Residual chromatic aberration optimized to a minimum.
- Temperature-compensating mount.
