The LS60THa is a complete Solar Telescope. The refractor based system
has a precision aligned singlet chromatic lens with a 60 mm aperture.
The front singlet lens reduces the stray-light over an achromat by half.
With the matched collimation lens set, it also fully corrects for on
axis coma, astigmatism and de-centering aberrations and provides a full
spherically corrected flat-field Solar-Telescope. The focal length is
500mm providing a ~4.5 mm image thru a 6 mm blocking filter. Fine
adjustment is achieved with a Crayford style focuser with 10:1
reduction.
An internal etalon with tune adjustment allows for a <0.8 Angstrom bandpass.
Delivered with order:
