TS Optics Flattener 1.0x (85742)
TS Optics Flattener 1.0x (85742)
221.28 $
Tax included
This flattener is a lens designed to correct the natural field curvature produced by the primary optics of a telescope. Without correction, this curvature can make stars at the edge of the field of view appear less sharp. The field flattener addresses this issue, allowing astrophotographers to capture images where stars remain sharp all the way to the edge of the frame. The flattener is placed between the telescope and the camera.

TS Optics Flattener/Reducer 0.8x (85704)
391.51 $
Tax included
This flattener is a lens designed to correct the field curvature caused by the primary optics of a telescope. Field curvature can make stars at the edge of the image appear less sharp. The flattener, or field flattener, corrects this issue, resulting in sharp stars all the way to the edge of astrophotography images. It is installed between the telescope and the camera. The reducer function shortens the focal length, which improves the aperture ratio of the telescope. This means shorter exposure times and faster optics.

This objective is designed for brightfield microscopy. The MAGUS Bio V360 microscope kit includes phase objectives, which contain a metal film ring etched onto the inner lens. This ring is required for phase-contrast observations, as it introduces a quarter-wavelength phase shift relative to the remaining light and reduces overall light transmission. For this reason, objectives without phase plates are recommended for standard brightfield observations.
