LM2 Optic Mount

Unique aluminum base design

The solid LM2 optic mount base and plate are machined from aluminum alloy and are protected with a non-shiny black aluminum oxide coating known as anodize. The unique design of the base is more rigid and has a higher frequency than flat mounts. The LM2's wide bottom provides superior mounting to tables or accessories. Thus, greater stability with less susceptibility to vibration.

Stainless steel adjustment screws in phosphor bronze bushings

The LM2 is equipped with three 1/4-80 adjustment screws each with 0.4 in. of travel. The adjustment screws are considered to have the finest resolution available today.

Dynamic range

The LM2 mount can be angularly adjusted to more than ±14.5° which leads to a beam deflection of ±29°.

Sapphire hard seat technology

We use a large 1/4 x 0.031 in. sapphire flat polished to optical standards on all LM2 mounts. The hard cylindrical vee is also standard on all LM2 mounts. These seats are so tough, they have been known to work flawlessly even when the mount has been dropped.

Nylon tipped set srews

Kinematically locates the optic and secures it without stressing or damaging it. They also allow for easy removal and replacement.

1/4-20 or M6 mounting hole

We provide the largest and strongest mounting holes to ensure stability. Deflections are solely the result of material elasticity.

Krytox fluorinated lubricant

Krytox greases have vapor pressures of 8 x 10^-8 to 6 x 10^-9 torr at 30 °C (100 °F) according to Du Pont and thus are unlikely to outgas on your expensive optics. Krytox also has a high degree of chemical inertness and outstanding oxidation resistance. Therefore, the adjustment screws will maintain their original smooth feeling if used daily, monthly, or yearly.

Metric

The standard mounting hole in the base is M6. The top set screw in the front plate is 8-32 UNC.
