• Internal RMS (0.800"-36) Threading
• Compact L-Shaped Mount
• 12.5 mm Optical Axis Height

The compact HCS013 microscope objective mount features internal RMS threading (0.800"-36) and has an optical axis 12.5 mm above the flexure stage. The internal RMS threading allows microscope objectives, components, or accessories with external RMS threads, such as our IR viewing screen (VRC2RMS), to be attached to one of our multi-axis flexure stages. Thorlabs also offers a complete selection of microscope objectives that are well suited for fiber coupling applications.

• Internal SM05 (0.535"-40) Threading
• Ideal for use with Our Ø1/2" Lens Tubes and SM05-Threaded Photodiodes
• 12.5 mm Optical Axis Height

The HCS020 mount integrates our extensive line of SM05-threaded (0.535"-40) components into our flexure stage systems. The optical axis of the SM05-threaded HCS020 mount is 0.49" (12.5 mm) above the flexure stage.

• Internal SM1 (1.035"-40) Threading
• Ideal for use with Our Ø1" Lens Tubes and SM1-Threaded Photodiodes
  
• 18.0 mm Optical Axis Height

The HCS031 mount integrates our extensive line of SM1-threaded (1.035"-40) components into our flexure stage systems. Due to the diameter of the SM1 threading, the optical axis of the HCS031 mount is 18.0 mm above the flexure stage.

Due to the higher optical axis, a 5.5 mm Height Adjustment Shim (AMA093) will be required for all mounts with an optical axis of 12.5 mm when used in conjunction with the HCS031.

HCS112 and Aspheric Lens with an HFB004 Fiber Holder on an MBT616D Stage

• Internal M8 x 0.5, M9 x 0.5, or M12 x 0.5 Threading
• Ideal for use with our Molded Aspheric Lenses
• 12.5 mm Optical Axis Height

The HCS108, HCS109, and HCS112 mounts have M8 x 0.5, M9 x 0.5, or M12 x 0.5 internal threads, allowing our line of Molded Aspheric Lenses to be used with our flexure stage systems. The optical axis of the mount is 12.5 mm above the flexure stage, giving a 75 mm optical axis height when fitted. The mounts are supplied with two AMA010 mounting cleats, together with 6-32 and M3 cap screws. Additional AMA010 cleats are sold at the bottom of the page.

For applications where space is limited or when multiple lenses need to be stacked next to one another, see the range of thin-profile lens holders below.

AMA110 mounting block shown with two HCS209 optic mounts in a close-coupled configuration.

• Only 6 mm Thick
• Internal M8 x 0.5, M9 x 0.5, or M12 x 0.5 Threading
• Allows Back-To-Back Lens Mounting
• Ideal for use with our Molded Aspheric Lenses
• 12.5 mm optical Axis Height

The HCS208, HCS209, and HCS212 mounts are a series of extra slim mounts for lenses and optics. They have M8 x 0.5, M9 x 0.5, or M12 x 0.5 internal threads and allow our line of Molded Aspheric Lenses to be mounted back-to-back. The optical axis of the mount is 12.5 mm above the flexure stage, giving a 75 mm optical axis height when fitted.

The mounts are supplied with two AMA010 Mounting Cleats, together with two 6-32 (M3) cap screws. Additional AMA010 cleats are available below.

For ultra close mounting, we also offer the AMA110 mounting blocks. These mounting blocks feature a line of nylon-tipped setscrews to secure the optic holders. They allow easy repositioning and very close mounting of multiple HCS2xx Optic Mounts (see image right). The blocks, which must be ordered separately from the lens mounts, are secured via two holes and are supplied with either 6-32 or M3 cap screws. Our AMA111 narrow optic clamps offer an alternative solution where devices need to be mounted close together. Two clamps are included, and both 6-32 and M3 cap screws are supplied. The AMA110 and the AMA111 are sold below.

• Holds Ø1 mm to Ø3 mm Gradient-Index (GRIN) Lenses
• Easy-to-Use, Simple Spring Clamp for Lens Retention
• 12.5 mm Optical Axis Height for Ø1.8 mm GRIN Lenses

The HGI003 gradient-index lens holder easily secures gradient-index lenses, with diameters ranging from 1 to 3 mm, in a precision V-groove with a spring clamp. This mount fits into the locating keyway of our multi-axis flexure stages. The keyway allows the GRIN lens to be slid into coarse position before securing. Final positioning is accomplished using the precision control of the stage. Gradient-index lenses are used to collect and focus light from laser diodes into optical fibers, to collect and collimate light from laser diodes, or to focus collimated beams into fibers.

CFS2 Pigtailed Aspheric Collimator Mounted in a HCS004 Flexure Stage Mount

• Two Setscrews and a Double-Bored Mounting Hole for Maximum Stability
• Models for Ø4 mm, Ø11 mm, Ø12 mm, and Ø15 mm Collimation Packages
• Designed for Multi-Axis Flexure Stages
• 12.5 mm Optical Axis Height

These collimation package mounts feature a 3 mm wide keyway in the base of the mount for compatibility with our line of multi-axis flexure stages. Our HCS004, HCS011, HCS012, and HCS015 Mounts are designed for Ø4 mm, Ø11 mm, Ø12 mm, and Ø15 mm collimation packages, respectively. Please see the table below for more details and for a list of compatible items.

Two setscrews with a 5/64" (2.0 mm) hex are used to press a collimator against the two lines of contact created by the double-bored mounting hole. Each mount is supplied with two AMA010 Mounting Cleats and two 6-32 and M3 cap screws for attachment to the multi-axis flexure stage. Additional AMA010 cleats are available below.

• Only Compatible with "Cross Style" Flexure Top Plates [Item # MMP1(/M)]
• 12.5 mm Optical Axis Height
• Holds Ø1" Optics

The HCS030 holds Ø1" (Ø25 mm) optics with the optical axis 12.5 mm above the flexure stage. A Delrin^®* pin is used to secure, without marring, the optic.

Note: the HCS030 must be used with flexure stages that feature the "cross style" top plate [MMP1(/M)] to provide clearance for Ø1" optics. The flexure stage top plate is easily replaced and is standard on all stages and accessories shipped after February 2006.

While we offer an extensive line of fiber launch and waveguide accessories, it is difficult to anticipate all of the possible requirements that may arise for customers. Hence, we have added these simple components, which ease the production of one-of-a-kind mounting accessories. As can be seen in the photograph to the left, the front surface of each blank is clearly marked with witness lines, which are centered on the 12.5 mm high optical axis of our multi-axis flexure systems.

• Secures Components to NanoMax, MicroBlock, or RollerBlock Stages
• Cleats for Mounting Single Components
• Mounting Blocks and Clamps for Close Proximity Mounting of Multiple Components

The AMA010(/M) Cleats have a flat milled along one side. To lock an accessory along the center alignment groove, rotate the cleat so that the flat is facing the groove. Place the accessory into the groove between the cleats, rotate the cleat so that the rounded edge covers the edge of the mount, and lock down the 6-32 (M3) locking screw and washer. The cleats can be rotated without needing to remove the locking screws. See the animation to the right for details. The included screws are 5/16" (8 mm) long and are used with a 3/32" (2.5 mm) hex key.

For mounting multiple components in close proximity, we offer the AMA110 mounting blocks. These mounting blocks feature a line of nylon-tipped setscrews to secure components, and allow for easy repositioning and very close mounting. The blocks are secured via two holes and are supplied with either 6-32 or M3 cap screws.

The AMA111 Narrow Device Mounting Clamps offer an alternative solution when devices need to be mounted close together. They are secured using an M3.5 or M3 washer and a 6-32 or M3 cap screw, compatible with a 7/64" or 2.5 mm hex key, respectively.
