Coating

Modified Stock Component Services

Edmund Optics offers extensive coating capabilities for optical components operating throughout the ultraviolet, visible, and infrared spectra. Coatings can be applied to uncoated substrates such as lenses, windows, or prism faces to modify performance characteristics or to create specialized optical components including beamsplitters and optical filters.

Available Coatings:

  • Standard Anti-Reflection and High Reflection Coatings can be applied to uncoated substrates such as lenses, windows, prism faces.
  • Broadband or Laser Line Designs available covering UV, Visible, and Infrared Wavelengths

Quick Modifications to Component Dimensions

Customize lenses, mirrors, windows, beamsplitters, polarizers, and prisms in 2-3 weeks!

Diameter Reduction

Diameter Reduction

Need an optic of a specific size? We can quickly and easily reduce the outer diameter of our off-the-shelf optics to meet your exact requirement.

Application Examples:

  • Exact/precision fit an optic to your lens barrel
  • Match filter diameters to your unique system
Typical Tolerances
Starting Part Size 6 – 400mm
Minimum Finished Diameter 3.5mm
Diameter Tolerance ± 0.1mm
Clear Aperture 80%
Beam Deviation 3 - 5 arcmin
Bevel Angle Tolerance 45° ±15°
Edge Chips = 0.50mm
Surface Quality 80-50

Truncation

Truncation

For design applications requiring a unique shape, a truncated lens, window, or mirror may be the best option. A truncation occurs when one or more straight cuts are applied to a round optic.

Application Examples:

  • Remove excess material in weight-sensitive applications
  • Custom mounting and fixturing
Typical Specifications
Starting Part Size 5 – 300mm
Minimum Finished Size 3.0mm
Maximum Thickness 30mm
Truncation Width Tolerance ± 0.1mm
Beam Deviation 3 - 5 arcmin
Bevel Angle Tolerance 45° ±15°
Edge Chips = 0.50mm
Surface Quality 80-50

Linear Cut to Size

Linear Cut to Size

Need a custom sized or shaped optic? We can cut any optic to meet your needs. For thin, flat optics, we offer an economical and easily repeatable scribe and break process. For thicker optics, our expert team may use precision saw cuts to create the desired geometry. A linear cut to size is not limited to only flat optics; the process can also be applied to optics with curved surfaces. For instance, a PCX lens can be modified from having a circular diameter to having a square outer edge.

Application Examples:

  • Remove excess material in weight-sensitive applications
  • Custom mounting and fixturing
  • Custom viewing windows
Typical Specifications
Starting Part Size 5 – 300mm
Minimum Finished Size 3mm
Maximum Thickness 30mm
Truncation Width Tolerance ± 0.1mm
Bevel Angle Tolerance 45° ±15°
Edge Chips = 0.50mm
Surface Quality 80-50

Edge Blackening

Edge Blackening

Is stray light interfering with your system’s performance? Stray light is energy outside of the clear aperture of an optical system that scatters off of the edges of an optical or mechanical component and reaches the sensor in the form of noise. Because stray light contributes noise rather than signal, stray light is a common limiting factor in overall performance of multi-element systems. To minimize stray light, we can edge blacken an optic using an RoHS compliant, solvent-resistant ink and improve overall light throughput.

Application Examples:

  • Improving image quality in imaging systems
  • Maximizing light throughput in optical systems
Typical Specifications
Starting Part Size 3 – 250mm
Minimum Finished Diameter +0.1mm added
Clear Aperture unchanged

Core Drilling

Core Drilling

Need to make dimensional adjustments to a filter? We can use a core drill to separate the filter substrate from the mount while retaining optical performance in the filter's central aperture. Once removed from the mount, the optic can be further modified with diameter reduction, truncation, or edge blackening.

Application Examples:

  • Creating a custom diameter for a filter
  • Filter mount removal
Typical Specifications
Starting Part Size 6.5 – 50mm
Minimum Finished Diameter 3.0mm
Diameter Tolerances ± 0.5mm or better
Clear Aperture 80%

Through-Hole

Through-Hole

In certain specialty applications, a through-hole in an optic may be required. We can drill through-holes to help simplify the optic mounting process or to enable compatibility with specific application requirements.

Application Examples:

  • Primary mirror of a reflective telescope
  • Combining laser beams
  • Custom mounting holes

Engraving

Engraving

Need a specific marking, engraving, or serialization to help monitor and track prototype assemblies throughout the development process, brand components, or ease identification? We can help.

Application Examples:

  • Apply a logo to the anodized aluminum barrel of an assembly
  • Two nearly identical lenses being dropped into a lens tube? Engrave the edge with letters or numbers to indicate their order when assembling
  • Create component position indicators along the surface of a breadboard
  • Add a fiducial mark to a set of polarizers to indicate the direction of linear polarization

Quick Modifications to Optical Surfaces

Surface Improvement

When you need performance beyond what a standard off-the-shelf component provides, Edmund Optics offers an advanced surface finishing process to optimize the performance of your optical system. Our engineers have successfully demonstrated the ability to improve optical surfaces to better than λ/10 irregularity (at 632.8nm).

Application Examples:

  • Improve imaging lens surfaces to potentially improve image quality
  • Reduce surface irregularity of a lens for use in a high power laser system

Surface Improvement 15 - 60mm λ/10 or better Central 80% diameter

Sphere to Asphere

Sphere to Asphere

A single aspheric lens can often outperform several spherical elements, particularly in fast optical systems (low f/#). Edmund Optics is pleased to offer this service to convert our spherical singlets to customized aspheric lenses by modifying one of our over 150 different stock PCX lens designs. Whether you have an aspheric lens already designed or only a preliminary setup, our engineers will work with you to help specify the right aspheres for your application. Learn more about using PCX lenses to create aspheres here.

Application Examples:

  • Reduce lead time and cost by modifying a stock PCX lens rather than submitting a fully custom request
  • Simplify imaging system prototyping by only producing the number of aspheres that you require
