Capabilities


Materials

Fused Silica is our go-to material. Schott, CDGM, and Corning glasses are available.  See the preferred glass list below.

Geometries

Using Laser-chemical Processing, we create freeforms and highly aspheric surfaces, cylinders, phase masks and plates, lens arrays, diffusers, beam-shaping optics, collimators, and multi-aperture optics 

With femtosecond laser ablation, we can create holes, notches, texturing, scribing, and vias in glass, metals, and ceramics.    Specifically, we can create through glass vias (TGV).

Services

Optical and mechanical design, part assembly, and custom flat-top generators are a core competencies.

Sizes

Edge diameter (mechanical diameter) from 2-25 mm.  Clear aperture diameter 0.5-25 mm.  As a percentage of the edge diameter, a  clear aperture of nearly 99% is possible for most optics.

For flat windows we can manufacture a variety of sizes from 3mm to 300 mm from most glass materials.

Coatings

 AR coatings 250-12000 nm and HR 350-20000 nm on parts 2 - 370 mm in diameter.  We also offer custom coatings.

Lead Time

 Accelerated turn around as fast as 5 days for in-stock materials.

Momentum Optics specializes in rapid, affordable, optics manufacturing.   We offer custom:

  • lenses (spheres, aspheres, and freeforms)
  • phase plates and masks
  • mirrors (off-axis, freeforms) 
  • glass laser machining (holes,  notches, through glass vias, channels and even fluidic structures) using almost any glass type as well as metals and ceramics. 
  • Coatings including anti-reflection (AR), high-reflective (HR) or mirrors and filters.  We have 21 standard coatings to choose from.   

Need something not listed here or easily defined, contact us!  We want to take on the most radical and challenging optics out there.  

Pricing is determined by a number of factors such as depth (sag) of the part, symmetry, material, selected tolerances, and desired turnaround.  We aim to be as transparent as possible.  To see the parameters that drive the cost of your specific part,  change one parameter at a time within the quote page and observe the real-time price change. 

Reach our customer support team by emailing info@momentumoptics.com.  We aim to respond to emails within 24 hours.  


We offer a 30 day warranty for all products found to be defective or perform outside of specifications.  Please request a return of merchandise authorization (RMA) before returning a product by emailing info@momentumoptics.com.  Refunds are processed within 7-10 business days of receiving the returned items.
