RelayPlus 1X-16-i

Very High performance lens with integrated telecentric vertical illumination 

 

Parts of the lens as shown above:

    Dark grey:                   Beamsplitter body, input to lens is show in lower right picture

    Medium blue barrel :  Main body of lens containing lenses

    Light blue barrel:       Illuminator with adjustable iris (purple)

    Orange:                       Camera mount (fitted with C-Mount adapter)

    Black:                          Camera simulation (camera not included)

Dimensions:                    Height: 260 mm tall

                                        Width:  120 mm + ~30 mm for camera mount

                                        Thickness:  66 mm (barrel diameter near iris ring)

Specifications:          

     NOTES:  When the lens is stopped down, the usable field size increases.  The illuminator is designed for

                     optimum performance at lens aperture F/6.  The illuminator field size will not cover field sizes

                     of lens at larger F/# lens settings.  If you plan on only operating the lens at only the larger

                     F/numbers (F/14 to F/50), let us know, and we can change the illuminator accordingly.

Magnification:                     1:1 (1X) Image same size and same F/# (N.A.) as object

Telecentricity:                     Double telecentric 0.05 degrees worst case at F/6

CCD formats accepted:        1/4 (3.2 x 2.4),   1/3 (4.8 x 3.6),   1/2 (6.4 x 4.8),   1/1.8 (7.2 x 5.4),

 (at F/6)                              2/3 (8.8 x 6.6),   2/3+(10.6 x 7.8),   1.0(12.8 x 9.6)

Maximum F/# (N.A.)             F/6 (0.083)   Continuously adjustable via built in iris - see table below:
