MC-T2 Series 60mm Cage-Style Adjustment Mirror Mounts

Product Description

Compatible with mounting Ø2-inch (Ø50.8mm) optical components on the optical axis, and works with 60mm cage systems.

Offers a pitch and tilt adjustment range of ±3°.

Through holes for installing Ø6mm cage rods.

M4 threaded holes on three sides for rod installation.

The adjustment mount provides ±3° pitch and tilt adjustment for optical components. The pitch and tilt adjustments are actuated by three 100 TPI (Threads per Inch) adjustment screws, enabling smooth, high-resolution movement. These adjusters feature a locking collar design and removable knobs.

Technical Description

Optical Knowledge Point: Common Optical Thread Size Standards

This is a thread specific to Thorlabs Inc. (USA) and not a commonly used optical thread. “SM” is the code for sewing machine threads in thread notation, but this American company uses it for internal and external thread connections of optical lenses and sleeves. The thread type is UNS (Unified National Special Thread) with a tolerance class of 2A/2B. A unique feature of this thread is that regardless of the diameter, the pitch is 40 threads per inch (TPI). Specific dimensions are as follows:

Series	Type	Thread (in)	Nominal Diameter (mm)	Minor Diameter (mm)	Pitch Diameter (mm)	Major Diameter (mm)
SM05	Internal	0.535-40	13.59	12.98±0.07	13.24±0.05	＞13.59
SM05	External	0.535-40	13.59	＜12.78	13.10±0.05	13.50±0.05
SM1	Internal	1.535-40	26.29	25.68±0.07	25.95±0.05	＞26.29
SM1	External	1.535-40	26.29	＜25.48	25.79±0.05	26.19±0.06
SM2	Internal	2.535-40	51.69	51.08±0.075	51.35±0.075	＞51.69
SM2	External	2.535-40	51.69	＜50.87	51.18±0.05	51.59±0.05

Product Description

The adjustment mount provides ±3° pitch and tilt adjustment for optical components. The pitch and tilt adjustments are actuated by three 100 TPI (Threads per Inch) adjustment screws, enabling smooth, high-resolution movement. These adjusters feature a locking collar design and removable knobs.

 

The MC-T2 has SM2 (2.035”-40) threads and includes 1 SM2 retaining ring and 1 Ø2-inch washer to fix optical components. In contrast, the MC-S2A uses nylon-tipped set screws to secure optical components, which can be tightened with a 2mm hex wrench or ball-head screwdriver.

Compatible with mounting Ø2-inch (Ø50.8mm) optical components on the adjustment mount. The MC-T2 can mount thinner optical components (up to 6.5mm thick), while the MC-S2A is designed for thicker optical components (minimum thickness of 5mm).

(4) The mount surface is equipped with 4 Ø6mm through holes, compatible with our PCM-S cage rods. The sides include four fixing screws; use a 1.5mm hex wrench or ball-head screwdriver to tighten the fastening screws and secure the cage rods in place.

(5) Each of the three sides is equipped with M4 threaded holes for installing rods in free-space setups.
