Thorlabs matched aspheric pairs provide near aberration-free one-to-one imaging. Each of our matched aspheric pairs consists of two identical aspheric lenses pre-aligned and mounted in a metal housing with a 11 mm x 0.5 mm external thread for ease of mounting. Our matched pairs are available with numerical apertures of 0.40 or 0.25 and with anti-reflection coating for 600-1050 nm or 1050-1600 nm.

To mount our matched aspheric pairs a RMS11P can be used to adapt the matched pair to standard RMS threading. To further mount the lens air into our Lens Tubes, an SM1A3 is recommended to mount any RMS threaded component into SM1 tubes. Additionally, to mount the matched pair on to our flexure stages an RMS11P can be used in conjunction with an HCS013 mount. Using the RMS thread adapter the lens pair can also be mounted to our KM100R Kinematic Mount.

Our High NA fiber coupling lens pairs provide an easy and effective solution for the routine task of coupling a laser diode to a multimode fiber. To provide the ability to easily launch the light from the divergent output of a diode to a high NA fiber the mounted lens pair consists of two lenses, one with a numerical aperture of 0.55, for the laser side, and the other with a numerical aperture of 0.25, for the fiber side. The lens pairs are available with anti-reflection coating for 600-1050 nm or for 1050-1600 nm.

The lens pair is pre-aligned and mounted in a metal housing with an external 9 mm x 0.5 mm thread on the side designed to face the laser diode. To mount the lens pair Thorlabs designed the S1TM09 adapter to adapt the housing to SM1 threading. This adapter allows to further mount the lens pair into our Lens Tubes. Additionally, to mount the matched pair on to our flexure stages a RMS thread adapter RMS09 can be used in conjunction with an HCS013 mount. Using the RMS thread adapter the lens pair can also be mounted to our KM100R Kinematic Mount.

Our fiber coupling lens pairs provide an easy and effective solution for coupling a laser diode to fibers with a numerical aperture above 0.16. To provide the ability to easily launch the light from the divergent output of a diode to a multimode fiber the mounted lens pair consists of two lenses, one with a numerical aperture of 0.55, for the laser side, and the other with a numerical aperture of 0.16, for the fiber side. The combination of the high NA, short focal length and the lower NA, longer focal length reduces the NA of the emitter by the ratio of the focal lengths. The size of the emitter is simultaneously magnified by the inverse of this same ratio.The lens pairs are available with anti-reflection coating for 600-1050 nm or for 1050-1600 nm.
