Laser Shelves are optional breadboards. They save space when installing a laser and other equipment beneath optical table tops. A shelf stays mechanically coupled to the table top. The shelves have a pattern of M6 holes.
Model 792-02 has M6 screws to attach directly to the bottom of a table top. So it can be used with any table top, with any support, or vibration isolation. Location of attachment (holes) can be standard, or specified by a customer.
