How to unpack and install the Zygo Mark II 4-inch interferometer system?

Specific cleaning procedures (methanol/acetone is toxic and flammable, caution is required; do not rinse the optical surface with flowing liquid to prevent damage to the seal/bonding area; consumables cannot be reused):

Loose particles on uncoated surface: Fold the lens paper into a 2-inch square pad, dip it in methanol (without dripping water), gently scratch the circular surface from the center outwards to wipe (change the pad every time), and wipe the square/rectangular surface from one end to the other.

Loose particles on the coating surface: Fold the Multilith pad in half four times, dip it in acetone (without dripping water), and wipe it according to the corresponding shape.

Semi solid pollutants on coated/uncoated surfaces: Dip the Multilith pad in Orvus solution (without dripping water) and gently wipe the contaminated area (according to the corresponding shape, do not scratch); Dip the pad in distilled water to wipe off Orvus; Dip the pad in methanol again to absorb residual moisture; Finally, change the pad and dip it in acetone, slowly wipe it in one direction and "lift it off" to finish (without dragging it to the edge), repeat until there are no traces of acetone; If there are still stains, the entire process needs to be repeated.

Special Warning: Zygo does not recommend cleaning high reflectivity soft coatings on transmission/reference components. If cleaning is necessary, the risk of damage must be borne by the user.

Maintenance of video monitor: no user serviceable parts, the shell is cleaned with a damp cloth or mild spray cleaner, and the screen is wiped with a commercial glass cleaner or a special cleaner for computer screen, and the fault needs to be sent back to Zygo for maintenance.

Laser head replacement: The laser head can be used normally for many years without any faults. If the output power is too low or the vibration stops, please refer to the "Service Manual SP-0038" for replacement and use Zygo original accessories.
