Single spherical lenses

Convex lenses

Convex lenses are optical imaging components with

positive focus length. After going through the convex

lens, parallel beam of light becomes convergent.

Concave lenses

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,

only.

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

a line.

Achromats

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

optical sets.

We. not only realise purchase orders according to

the customer specifications, but make our own

calculations, optics designs and mechanics as

well.

Triplet

Huygens eyepiece

Kepler telescope expander

The range of our service is as follows:

objectives,
oculars,
condensers,
lunettes,
laser expanders,
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.
