Thorlabs' VM05(/M) Compact Kinematic Mount with Vertical Drive features top-mounted, 0.25 mm pitch actuators designed to keep the beam path clear, which is ideal for use with high-power lasers. Sensitivity is achieved by two fine adjustment screws that offer a 1/2° of angular adjustment per revolution. Each knob can be rotated by hand or by using a 5/64" (2.0 mm) hex key or balldriver. The VM05(/M) mount offers a total angular range of ±3° and a Ø0.44" (11.2 mm) clear aperture. A nylon-tipped locking setscrew secures the Ø1/2" optic. The mount's thick main body increases rigidity to prevent flexing during adjustment. ![]()
Thorlabs' VM1(/M) Compact Kinematic Mount with Vertical Drive features top-mounted 100 TPI actuators designed to keep the beam path clear, which is ideal for use with high-power lasers. Sensitivity is achieved by two fine adjustment screws that offer a 1/4° of angular adjustment per revolution. Unlike the VM05(/M), the screws at the end of the knob cannot be used to rotate the knobs. The VM1(/M) mount offers a total angular range of ±3° and a Ø0.94" (23.9.2 mm) clear aperture. A nylon-tipped locking setscrew secures the Ø1" optic. The mount's thick main body increases rigidity to prevent flexing during adjustment. ![]() ![]() Click to Enlarge Using the POLARIS-K1VS2 Ø1" Mount: A: POLARIS-T2 Tool for Adjusting POLARIS-LNS1 Collars B: 5/64" or 2.0 mm Hex Key in the End of an Adjuster C: POLARIS-N5 Removable Knobs on the Adjusters* D: HKTS-5/64 Hex Knobs on the Adjusters ![]() Click to Enlarge Mount Shown with Optional POLARIS-N5 Removable Knobs* (Not Included)
This 2-Adjuster Ø1" Polaris Kinematic Mirror Mount provides long-term stability and high-resolution adjustment using vertical drives. This design allows for adjustment in situations where there may not be space behind the mount for horizontal access to the adjusters. To secure an optic, the mount uses a monolithic flexure arm that can be actuated using the included screw and a 0.05" (1.3 mm) hex key. The monolithic flexure arm design keeps wavefront distortion on the mounted optic to a minimum while providing strong optic retention force (see the full web presentation for details). The 2-adjuster design improves mount stability by limiting the available degrees of freedom for movement. The monolithic front plate and stiff springs used in the construction of the POLARIS-K1VS2 mount provide enhanced stability and reduced optic distortion, making this mount an ideal solution for OEM applications that require reliable operation in rugged environments.
Product Highlight: Polaris Vertical Mirror Mount
The 100 TPI adjusters feature a 5/64" (2.0 mm) hex and may be adjusted with our HKTS-5/64 Hex Key Thumbscrews, the hex on the end of the SA1 Adjustment Tool, or any other 5/64" (2.0 mm) hex wrench. Alternatively, POLARIS-N5 removable, low-profile adjustment knobs can be threaded onto the adjusters for improved feel in fine-resolution adjustments, although mechanical angular range may be reduced. The adjusters on this mount can be locked using the POLARIS-LNS1 locking collars. Two are pre-installed on the POLARIS-K1VS2, one for each adjuster. The included locking collars can be loosened or tightened most easily using the POLARIS-T2 spanner wrench. Post mounting is provided by two #8 (M4) counterbores. For custom mounting configurations, two Ø2 mm alignment pin holes are located on each mounting face for setting a precise location and mounting angle. Standard DIN 7-m6 ground dowel pins are recommended (click on the red documents icon below for details). We recommend using this mount with a stainless steel post that also has Ø2 mm alignment pin holes, such as our Ø1" Posts for Polaris Mirror Mounts. *POLARIS-N5 Removable Knobs thread directly onto the exposed adjuster screws. Using them on the POLARIS-K1VS2 may result in a reduced mechanical angular range. | |||||||||||||||||
