Single spherical lenses
Convex lenses are optical imaging components with
positive focus length. After going through the convex
lens, parallel beam of light becomes convergent.
Single concave lenses spread, optical imaging
elements with negative focal length. Collimated beam
of light going through the lens becomes divergent and
thus the image obtained is virtual. It can be observed
through the lens in the incident direction of the light,
Meniscus (Concave-convex lenses)
One surface of meniscus lenses is concave, while
the other – convex one. A meniscus lens is almost
always used in combination with other kinds of lenses
to build systems with focal length shorter or longer
than that of the original lens.
Single cylindrical lenses
Cylindrical lenses are optical imaging components
with one of the surfaces being cylindrical instead of
spherical. The second surface in this kind of lenses is
usually flat. As the cylindrical surface deflects the rays
in one direction only, it transforms the point image not
into a point as in the case of spherical lenses, but into
Achromats are optical components composed of
lenses produced from different materials for correction
of chromatic aberrations. An achromat, which consists
of two lenses, is called achromatic doublet.
Sets of lenses
We produce mounted as well as not mounted
single lenses, cemented as well as not cemented
doublets, triplets, and more complicated complete
We. not only realise purchase orders according to
the customer specifications, but make our own
calculations, optics designs and mechanics as
Kepler telescope expander
The range of our service is as follows:
special custom lenses and sets.
According to customer specification, we can deliver non-standard lenses with significantly higher
optical parameters: 10-5; λ/20 (633nm), for example. Lenses in mountings – also if requested.
