An optical system comprising includes an off-axis folded three mirror anastigmat (TMA) telescope including a primary mirror for receiving energy from a scene. A secondary mirror is aligned to receive reflected energy from the primary mirror. A fold mirror is aligned to receive reflected energy from the secondary mirror. A tertiary mirror is aligned to receive reflected energy from the fold mirror and to direct energy between the secondary mirror and the fold mirror. A beam splitter is aligned to receive energy reflected from the tertiary mirror, to reflect a portion of that energy to a first imaging sensor, and to pass a second portion of that energy to a second imaging sensor.

Modular reconfigurable optical systems for supporting multiple modalities

A cooling system includes a first dewar configured to house a first optical imaging device, a second dewar configured to house a second optical imaging device, and a Stirling cycle refrigerator. The Stirling cycle refrigerator can include a compressor, a first expander in fluid communication with the compressor and in thermal communication with the first dewar, and a second expander in fluid communication with the compressor and in thermal communication with the second dewar.

Multi-dewar cooling system

A beamsplitter includes an optical substrate with a first surface configured to receive a beam of multi-spectral light, to reflect a first band of the multi-spectral light and to transmit a second band of the multi-spectral light through the optical substrate to be emitted from a second surface of the optical substrate opposite the first surface. The second surface is a freeform surface. A system includes a telescope configured to focus multi-spectral light into a beam. The system also includes a beamsplitter as described above optically coupled to the telescope so the first surface of the beamsplitter is configured to receive the beam of multi-spectral light from the telescope.

Aberration correction

An image forming system and lens system including at least one molded chalcogenide lens element and configured to simultaneously image light at the medium wave infrared region (MWIR) and the long wave infrared region (LWIR) at a common focal plane.

Dual band lens system incorporating molded chalcogenide

An image forming system and lens system configured to simultaneously image light at the short wave infrared region (SWIR) and the near infrared region (NIR).

Method and system for simultaneously imaging in the near infrared and short wave infrared spectrums

A method for providing optical alignment for a visible wavelength reflective system is provided. The method includes positioning a first mirror blank on a lathe fixture. The first mirror blank comprises a single precision pinhole. The first mirror blank is secured to the lathe fixture. A first mirror is generated from the first mirror blank.

Method and system for providing optical alignment for a visible wavelength reflective system

A system and method for optical alignment of a color imaging system includes illuminating a target plate with a laser beam. Photo-luminescent energy from the target plate is emitted in response to the laser beam. A color imaging system is aligned based on the photo-luminescent energy emitted at the target plate.

System and method for optical alignment of a color imaging system

An apparatus for processing optical signals includes a cladding material having therein at least two elongate core regions which serve as respective waveguides. A coupling portion therein includes adjacent and parallel portions of the two waveguides which extend sufficiently closely for a sufficient distance to permit coupling of radiation between these waveguide portions. Structure is provided that respectively permits and frustrates such coupling for respective component signals having respective different wavelengths. The coupling portion may optionally include an externally controlled switching section that can have a selected one of two states in which is respectively transmissive and nontransmissive to radiation.
