Mirror Holders

Each optics holder has its feature, there is always a holder fit your application.

Kinematic Center Mirror Mount

The mirror reflective surface of these kinematic mirror holders is not offset from the axis of the post even when the mirror thickness changes.

C-Shape Stainless Steel Mirror Holders

This mirror holder is made by stainless steel and optimized for 12.7 mm dichroic mirrors and beamsplitters.

High Precision Kinematic Mirror Mounts

Precision 0.1mm thread pitch fine adjustment screw introduces high resolutions. It is thinner than MHG mounts.

Kinematic Mirror Mount

Improvement of the conventional design of kinematic mirror holders (MHG) brought a further reduced price.

NOMI LOCKTMModel Kinematic Mirror Holder

High stability Kinematic Mirror Holder with SIGMA KOKI’s unique locking mechanism (NOMI LOCKTM).
NOMI LOCKTM is a new type of locking mechanism that enables adjustment of the torque of adjustment screws.

Kinematic Mirror Holders

Remarkably stable and compact. Suitable for use close to other devices. Offers a sufficiently large, clear aperture for 45° incident beam.

Options for Kinematic Mirror Holders

Post Adapter Plates

Plates for correcting the offset between the center of mirror reflective surface and the holder mounting position.

45° Optics Adapters

Used when directing the beam vertically up (or down) using kinematic mirror holders (MHG) installed on optical benches.

Adapter Mounts

Adapters for mounting smaller diameter mirrors.

Laser Mounts

Adapter for mounting laser diodes (LDU33) with kinematic mirror holders.

Base Plates for Kinematic Mirror Holders

When mounted on the breadboard, and vibration isolation, which enables the placement of lower optical axis.

Optical Path Switching Mounts

Mounts for removing and inserting mirror holders from optical paths in order to switch optical paths in a optical system.

Prism Adapters

Adapters for holding cube optics such as beamsplitters or prisms. Provide extended stability by fixing adjustment screws with NOMI LOCKTM.

Horizontal Prism Adapter

A prism adapter set that kinematic mirror holders to be used as prism holders while maintaining the operability of the kinematic mirror holder and ...

Small Kinematic Mirror Holders

Compact mirror holders with minimum necessary functions.
Appropriate for usage where operability of angle fine-tuning is not an issue and mirrors need to be placed within a limited space inside a device.

Mirror Case Adapters

Adapters for holding mirrors in compact mirror holders (MMHN-25) without adhesive.

Mirror Adapters

The adapter can be used to change the mounting position of the adapter relative to the mirror holder.

Gimballed Mirror Mounts

The gimbal structure allows the mirror angle to be changed freely at the rotational center of the mirror reflective surface.
Appropriate when dealing with laser beams or changing reflected beam orientation.

Gimbal Beamsplitter Holders

Gimbal mirror holders with narrow mirror frame for increased aperture at 45 degrees incidence.
Provide a transmitted beam diameter virtually the same as the reflected beam diameter.

Vertical Control Gimbal Mirror and Beamsplitter Holders

The space required for holder adjustment was eliminated from around the holder by making the control direction of adjustment screws vertical.
Holders can be installed close to each other, which significantly downsizes optical systems.

Beam Steering Holders

Beam steering mounts are designed to make it easy to change the height and direction of a laser beam.

Beam Steering Holders

It is a compact and simplified beam steering holder.

Precision Beam Steering Assembly

The φ38.1mm strut fitted with a vibration isolation function, and two top and bottom holders are a product set.


It is part of the mirror holder that is used for beam steering component.

Vertical Control Small Mirror Holders

Compact mirror mounts with vertical control. Small footprint. Vertical control realized compact layout with minimum horizontal extension.

One-touch Kinematic Mirror Holders

Mirror mounts with quick attachment feature and eliminated need for tools. Useful when optics are changed on a frequent basis.

One-touch Mirror Adapter

When mounted on the tilt mount, can be used as a mirror holder.

Topmike Vertical Control Mirror Holders

Kinematic mirror mounts accessible from top or side. Useful when mirror is located close-proximate of other optical devices or difficult to access. Both vertical and horizontal mounting is available with specially designed adapter plates.


By replacing the dedicated plates, the LMHB can offer various installation options.

High Rigidity Mirror Holders

High Rigidity Mirror Holders

MHL is kinematic mirror holder with blade spring. High rigidity can suppress the positional shift due to shocks or vibrations.

Base Plate for MHL

Base plates for MHL series mirror holders to maintain compatibility with MHB series.

Kinematic Mirror Holders

Kinematic mirror mounts with rigidity bracket and directly mounted to a baseplate. Usable as a holder of He-Ne laser or beam expander.

Vertical Control Gimbal Mirror Holders

Vertical Control Gimbal Mirror Holders

Gimballed mirror mounts accessible from top. Mirror angle is arbitrarily adjustable with its point of reflection unchanged. Useful when mirror is l...

Base plate for Gimballed Mirror Holder

It is a base plate for mounting the gimbaled mirror holder.

Close-proximity Mirror Holders

Gimballed mirror mounts with single side holding mechanism. Possible to layout two mirror mounts at close-proximate.

Larger Precision Gimbal Mirror Holders

Gimballed mirror mounts to hold large diameter mirrors over 100mm.
Optical distance is maintained at angular adjustment of large aperture mirror.


Base plates used for fixing larger precision gimbal mirror holders (MHD) on optical breadboards or optical baseplates.

Adaptor Mount

Mirror mount adaptor for specific (unsual) optics size.

Designed for high stiffness while minimizing the height of the stage.
