Product catalog summary

General Overview: Prisms are optical components used to manipulate light beams in optical systems. They can reverse, invert, or rotate images and are typically made from glass or transparent materials suitable for specific wavelengths.

Dispersion: Prisms utilize dispersion to separate white light into its constituent colors, similar to a rainbow effect, by refracting different colors at different angles.

Total Internal Reflection (TIR) Prisms: These prisms use internal reflection to substitute mirrors in certain applications, capable of splitting light into components with different polarizations.

Right Angle Prisms: Used for beam bending and retroreflection, suitable for visible and near-infrared wavelengths.

Fused Silica Right Angle Prisms: Made from UV-grade fused silica, ideal for UV laser and imaging applications due to high transmission and heat resistance.

Equilateral Prisms: Used for wavelength separation, refracting light twice with deviation depending on refractive index and wavelength.

Penta Prisms: Deviate light by 90 degrees without inverting or reversing the image, coated with aluminum for enhanced reflection.

45° Reflection Prisms: Used for beam deviation with aluminized reflecting surfaces for protection.

Right Angle Roof Prisms: Used in telescopes for image erection, featuring a roof edge on the reflecting face.

Corner Cube Prisms: Reflect light back to the source regardless of orientation, ideal for wide field of view applications.

Dove Prisms: Used as beam rotators, flipping and inverting images without lateral transposition.

Wedge Prisms: Used for small beam steering in optical systems.

Cylindrical Lenses: Focus or expand light in one axis, useful in optical metrology and laser scanning.

Wollaston Prisms: Separate non-polarized light into two orthogonal linearly polarized beams, used as polarizing beamsplitters.

Specifications: Include wavelength range, transmission, optical damage threshold, extinction ratio, and beamsplitting angle.

Mirrors and Reflectors: Include Laser Line Dielectric HR Mirrors, Broadband Reflection Mirrors, and Dual Wavelength Dielectric HR Mirrors, designed with high reflectivity coatings.

Optical Coatings: Enhance reflectivity and durability of mirrors, using metallic and dielectric materials.

Filters: Transmit specific portions of the light spectrum while blocking others, including absorptive, dichroic, and neutral density filters.

Interference Filters: Manipulate light based on wavelength, with specifications for center wavelength tolerance, peak transmission, and out-of-band blocking.

Beamsplitters: Divide an incident beam into multiple output beams, available in cube and plate forms.

Lenses: Include achromatic Fourier transform lenses, beam expanders, and laser focusing lenses, used for manipulating laser beams.

Applications: Optical components are used in laser systems, optical experiments, and applications requiring precise light manipulation.

Telecentric Lenses: Maintain constant magnification over a range of distances, minimizing perspective errors, ideal for precision measurement applications.

Optical Holders and Mounts: Include self-centering, platform and clamp, and kinematic mounts for precise alignment and adjustment.

Kinematic Optical Mounts: Designed with six independent constraints to eliminate three degrees of freedom without redundancy.

Gimbal Mounts: Allow for non-coupled rotation adjustments without translation.

Optic Holders and Stages: Include various holders and stages for precise positioning and alignment of optical components.

Mechanical Accessories and Motorized Stages: Include screw adapters, rod clamps, magnetic bases, post bases, rails and carriers, vernier micrometers, precision screws, breadboards, slits, iris diaphragms, and motorized stages.

Fiber-Coupled Laser Diodes: Available in compact, hermetically sealed packages for various applications.

Photodetectors: Include InGaAs and Silicon PIN photodiodes, used in optical measurement and analytical equipment.

Diode Laser Systems: Offer high power diode laser sources with customizable wavelengths and powers.

Each lens surface in contact with air passes approximately 96% of the light due to reflection. Therefore, optical surfaces are commonly coated with a thin dielectric film to enhance the light transmission. Anti-reflection coating generally consists of 1 to 5 layers (in special cases up to 50 layers) and reduces reflection losses down to 0.2%. The coated films need to be specially adjusted to the required wavelengths and glass types. We offer anti-reflection coatings for wavelength range from 350nm to 1800nm, as well as band pass filters, mirror-and beam splitter coatings and Dichroic filters....
