Description
The KERN OBB-A1290 is an low-strain infinity-corrected plan achromat objective delivering 20x magnification at a numerical aperture of 0,45. Its low-strain glass keeps the image free of stray birefringence.
Benefits
- Flat field: plan achromat correction for an edge-to-edge sharp, level image with no refocusing
- Resolution: numerical aperture 0,45 at 20x magnification
- Infinity optics: the parallel beam path takes filters or beam splitters without shifting the image
- Spring-loaded front: retracts on contact with the slide and protects front lens and sample
- Low-strain glass: suited to contrast and polarized-light techniques
