Mid-IR Isolators

Our Mid-IR Optical Isolators eliminate the annoying effects of feedback in quantum cascade laser applications and systems, operating at specific wavelengths from 4 μm to beyond 14 μm.

Standard wavelengths in stock are:

4.5 μm, 8.0 μm, 10.6 μm

These can be tuned more than ± 10% of center λ

Other wavelengths available. Please inquire.

It’s the IR that makes IR isolators difficult. The critical component in any isolator is the magneto-optic material that performs the rotation of the plane of polarization in the magnetic field. Whereas in the VIS and NIR there are many candidate magneto-optic materials, in the infrared the choices are greatly reduced. In our Mid-IR Isolators we utilize a very small family of highly specialized materials that demonstrate low absorption and acceptable Verdet Constant at the wavelength of operation.

The other critical component is the polarizer, and again, there are few choices in the infrared. See POLARIZERS in our Flat-Top Beam Expander and Fiber-Optic Coupling Lenses pages for descriptions of our IR Polarizers.

Escape Window option allows monitoring of feedback that is rejected by the Isolator. When ordering, specify Escape Window on Input or Out-put Polarizer.

λ: When ordering, specify wavelength between 4 μm and 14 μm.

4.5 μm ISOLATORS

4 mm aperture

Temporarily Not Available

This high performance, utility-sized isolator economizes on space requirement while utilizing novel design features that greatly reduce production costs, thus enabling a selling price that is far below competing products.

Our Mid-IR Optical Isolators eliminate the annoying effects of feedback in laser applications and systems, operating at specific wavelengths from 4 μm to beyond 14 μm.

FEATURES

Wavelength Tunable +/-10%
Transmission 75% to 86%
Isolation 10,000:1 (40 dB)

Other wavelengths available in utility-sized package.

The high transmission, high extinction polarizer is a size-reduced version of our PGC-5 WideBand IR Polarizer (see page 6). This Polarizer is characterized by extremely low insertion loss and extremely high extinction ratio.

WideBand IR POLARIZER 2 μm – 12 μm

InnPho’s unique Wideband IR Polarizer utilizes two precision polished Germanium plates at Brewster’s angle in “chevron” orientation. Low deviation, <10 seconds, with very high extinction and transmittance.

Cell length, 2.2”. See also ShortCell IR Polarizer below.

PGC-4: 15 mm Diameter x 36 mm long

PGC-5: 1-inch long x 2.2 inches long

ShortCell IR POLARIZER 3 μm – 11 μm

InnPho’s ShortCell IR Polarizer is used when short package length is important. Because of the delicacy of wire-grid polarizers, we have improved the mounting cell so that the hyper-delicate grid coating is protected from external contact. Cell is 12 mm thick.

Infrared Polarization Rotator

Broadband Achromatic, VIS to 9 μm*

*10.6 μm under development

Continuous Rotation Manual Control
Rotary Scale Readout 0º- 360º

• Rotates POP (Plane of Polarization) to any angle.

• Continuous Transmission VIS to 9 μm

• Coaxial Input-Output beams

Flat-Top Beam Expander

InnPho’s Flat-Top Beam Expanders convert a Gaussian laser beam input into an output that has a flat-top profile. The conversion is caused by an Engineered Diffuser™, manufactured by RPC Photonics, Inc.

• Spectral Range: 350 nm to 2 μm

• Cross section uniformity: ±5-10% (neglecting speckle)

• Laser damage threshold: 20 J/cm2, 1054 nm, 1 ns pulse

Optimum performance of the apodizing element (Engineered Diffuser™) is achieved when the input beam diameter is 3-4 mm, using our GCE-9.

GAUSSIAN COMPENSATING PLATE

Fiber-Optic Coupling Lenses

Coupling Lenses for VIS-NIR

InnPho’s Fiber-Optic Coupling Lenses are mounted in the industry standard RMS Threaded Mount favored in most laboratories. Transmittance of these AR-AR coated lenses exceeds 96% at the peak wavelength. Performance is diffraction limited when Maximum Beam Diameter is not exceeded; see below.

Antireflection Coatings

Mid-IR Focusing Objectives 2 μm to 12 μm

InnPho’s Mid-IR Focusing Objectives are designed for maximum efficiency in coupling the output from a mid-IR source into single-mode or multimode IR transmitting bers.

• ZnSe MicroLens

• AR-AR in Mid-IR

• Diffraction limited

• Easy alignment using HeNe

• Mounting RMS thread

• 2 μm to 12 μm

 TRANSMISSION

The ZnSe lens in LFO-Series Objectives is Broadband AR (BBAR) coat- ed on both sides. Transmission from 2 μm to 12 μm is 90% to 96%.
See graph above.

Fiber-Optic Collimators

Twist-On Collimators for VIS-NIR (425 nm – 1550 nm)

Twist-On Collimators connect quickly to FC or SMA connectorized fiber cables to produce a collimated beam.

Twist-On Collimators contain a micro lens that is designed for diffraction-limited performance. Both surfaces of the lens are antireflection coated, with >98% transmission at the peak wavelength.

Focal compensation for different wavelengths is achieved by a simple hand adjustment of the ne-threaded spring loaded focusing barrel.

λ: When ordering, specify wavelength for AR coatings

Twist-On Collimators are available with a choice of different focal length Lenses as follows:

Mid-IR Fiber Collimators

MID-IR Collimators for SMA Connectors (2 μm to 12 μm)

The same AR-AR coated ZnSe micro-lens used in our Mid-IR Focusing Objectives is used in our Mid-IR Collimators. These are designed to connect to SMA connectorized IR ber cables.

Our Mid-IR Collimators are focusable so as to compensate for different wavelengths. These are available “as is” or mounted in the 1-inch diameter Cell, which in turn mounts into our HTP Tilt Plate Positioner or any 1-inch laboratory X-Y stage.

λ: When ordering, specify wavelength for AR coatings.

A comment on Numerical Aperture… think of the NA of the fiber as a cone or a funnel… if the light rays are at an angle that is smaller than the cone angle, the light will get through the fiber.

2NA = d/f
d = laser beam diameter
f = focal length of lens

IR Fiber Cables

InnPho IR Fiber Cables are complete from laser in to collimator out. On the input end of an IR Fiber is a fully adjustable and stable InnPho Laser Port that can attach to a laser or mount remotely to provide stable coupling of the laser output into the IR Fiber Cable. On the output end is a focusable InnPho Collimator that contains an AR coated ZnSe micro-lens.
