Momentum Optics values your privacy and security.  You always own your data.  

We use best practices to maintain the confidentiality of your files.  We secure your data through encryption, strict access controls, and audits.   We only use your files in the quoting process to generate manufacturing specifications.  We do not store your CAD files following specification generation.  All data is processed on US based servers. The servers and network where data is stored are isolated by firewall, and only authorized staff can access it.  Customer data is not shared outside of Momentum's services.

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.
