The laser attachments D40 and D65 are useful for fast coarse alignment of autocollimators. They are especially handy for aligning distant or very small mirrors, polygons or prisms.

Please note: When using the laser attachment with an electronic autocollimator (ELCOMAT 3000, ELCOMAT vario or ELCOMAT direct) you do not need a power supply for the laser attachment because the attachment can be fed by the electronic autocollimator directly.

The AC-Finder Prism is designed for alignment of mirrors with respect to autocollimators at short distances.
