Custom off-axis parabolic mirrors for precision optics
High-performance diamond-turned OAPs for industrial and scientific applications
Millpond Optics excels in the manufacturing of custom off-axis parabolic mirrors (OAPs). Using ultra-precision single point diamond turning (SPDT) technology, we produce machined optics that deliver precise focusing without the limitations of chromatic aberration.
Whether your project requires individual prototypes or batch production, our metallic custom mirrors are engineered to meet the rigorous standards of space technology, automotive, LiDAR, and laser science.

Why choose Millpond Optics for custom off-axis parabolic mirrors?
Custom solutions for engineering challenges
As a leader in metal optics, we understand that off-the-shelf components rarely suffice for cutting-edge engineering. We work directly with your specifications to define the exact shape and focal requirements for your unique application.
Spectral versatility
Millpond Optics metallic mirrors serve as critical components in many kinds of sensing and imaging systems. Our mirrors maintain high surface integrity and reflectivity across a wide range of wavelengths. A multi-layer or dielectric coating may be added to the metal substrate to optimize for reflecting only one—or maybe two—wavelengths. Alternatively, it is feasible also to design coatings for a broader wavelength range.
That makes our optical mirrors ideal for:
- Remote Sensing & Space Technology: High-durability aluminium mirrors for satellite instrumentation.
- Automotive & Industry Automation: Robust precision machining for sensor and scanning systems.
- Bio-Analytics & Laser Science: Accurate focusing for specialized laboratory equipment.
- Other industrial and scientific purposes that require high accuracy and reliability.
We manufacture optical components in all manners of shapes besides off-axis parabolas, such as custom aspheric mirrors.
