Lens Mounting Tubes

Lens Mounting Tubes

  • Simple, flexible design
  • Independent cells all adjustment of lens groups without moving other groups.
  • Nested cells allow small optics to be easily mounted with larger optics.
  • Variety of lengths and diameters for mounting a single lens or multiple groups of multiple elements.
  • Metric threads common to other OptoSigma hardware and optics allow mixing of tube mounted optics with traditional mounts and optics holders.

Mirror Mounts

Mirror Mounts

OptoSigma offers a very wide selection of mirror mounts covering applications from stable inter-cavity optics to simple beam turning mirrors. When selecting a method of mounting mirrors it is important to consider the required stability, range and sensitivity of adjustment. The mechanical constraints of the system and ease of mirror replacement may also be important.

 

For the most stable mounting of mirrors it is best to use a base mounted mirror mount with a secure method of mirror attachment such as the “large precision”, Ultra-stable™ or TopMike™ mirror mounts. These types of mirror mounts restrict the range of angular adjustment but they do permit very sensitive adjustment. For a larger range of adjustment, choose a “gimballed” or “close-proximity” mirror mount. Both of these provide full 360 degree rotation of the mirror about the mid-point of its surface. “Bracket-type” and OneTouch™ mirror mounts provide an inexpensive and simple method of mounting which is suitable for most general purpose applications. The small mirror mounts are ideal for beamsteering in both experimental and OEM applications.

 

We have wide experience in manufacturing mirror mounts, so if you don’t see the exact solution to your mounting requirement described on the following pages - please call. Our engineers will be happy to assist you in selection of the most suitable mount for your application.

Optic Holders

Optic Holders

We offer a broad selection of component holders which suit the optical components listed earlier in this catalog as well as many others. Appropriate adjustments are included in most of the holders. Each holder is equipped with an 8-32 or M4 thread for mounting onto a post, pedestal or fixed base. Center heights are in multiples of 5mm and appropriate spacers are available to compensate for height differences within the system. For experimental and prototype use, these holders may be mounted onto optical breadboards or rails (described on pages 310-322) but they may equally well be incorporated directly into manufactured products.

 

Also offered in this section are products such as variable neutral density filters, calibrated iris diaphragms, adjustable slits, spatial filters, beam dumps and mini-system kits.

Optical Baseplates

Optical Baseplates

When it comes to using the optical components listed in the earlier pages of this catalog, the way the elements are mounted and positioned is very important. Optical component mounting requires a high degree of precision and stability. The mounting methods are of extreme importance to the correct functioning of the final optical system. Whatever system of positioners and holders is used, the mounts will only be as stable as the base to which they are attached.

 

We offer a selection of aluminum baseplates. These all have the industry standard 1/4- 20 by one inch (M6 by 25mm) hole pattern. Onto these bases can be mounted optical rails, rods, posts and a variety of mounts all of which are 1/4-20 (M6) by one inch (25mm) compatible.

Optical Rails and Carriers

Optical Rails and Carriers

When it is required to provide linear adjustment of the spacing of optical components over a wide range, the best way is to use a rail. The rails we offer have an extremely low profile so they do not cause excessive height build up. These rails are in the form of a dovetail. They are used with mating carriers which may be inserted at various points along the rail without interfering with adjacent carriers. Two widths of rail are offered, 50mm and 100mm. A series of slots along the centerline of the rail facilitates attachment to an optical table or breadboard. Both inch and metric hole spacings can be accommodated by the slots.

 

Alternatively the rails may be clamped using ledges along the sides. Each size of rail has its own series of carriers. These are attached by releasing the clamp screw and hooking the lip over the dovetail section on the rail. The clamp may then be loosely tightened to permit sliding or fully tightened to lock the carrier in place. On the upper surface of the carriers is a standard inch or metric mounting hole pattern which may be used to attach stages, post holders or other mounting devices. The surface is parallel to the base when in use.

Post, Post Holders, Clamps

Post, Post Holders, Clamps

Posts provide a simple means for mounting optical components. These posts are 1/2 inch in diameter and incorporate precision machined features which make them more convenient to use. Half inch diameter stainless steel posts are machined with a 1/4-20 or M6 female thread on one end and an 8-32 or M4 female thread on the other. They may be stud mounted to a wide variety of component holders. A 4mm clearance hole through the middle of the post provides for the use of a torque bar for tightening. Post collars are offered separately to hold the posts at a preset height. Post holders are made from aluminum and are equipped with a spring loaded clamp screw to hold the post in position. The base of the post holders is fitted with a 1/4-20 or M6 female thread for attachment to a variety of bases. An adjustable height post holder provides 10mm of vertical adjustment which is actuated by the rotation of a knurled ring.

Rod Mounting Systems

Rod Mounting Systems

These 1.5 inch diameter damped steel rods provide a very stable and vibration free method of mounting laser components. Both the rods and the mounts are completely compatible with most existing rod mount systems. Our mounts incorporate precision adjustment mechanisms which are easy to use yet very stable once set. The tilt mount is made to accept a range of replaceable OneTouch™ mirror holders. The beam steering units provide all essential features and operate in such a way as to maintain the beam centerline.
