A hybrid diffractive lens is a refractive optical element with a custom-designed diffraction profile encoded onto one surface. Such a hybrid literally combines the power of refraction and diffraction; as such, a single hybrid lens can replace two or more refractive lenses, especially when utilizing aspheric surfaces. Furthermore, because diffractive surfaces have “negative optical dispersion,” a hybrid lens can make an excellent single-element achromat(*). This technique of combining multiple lenses into single hybrid lenses enables optical designers to reduce the overall mass, volume, and material cost of an optical system.
Tier 1, 2 and 3 manufacturers in industries as diverse as military, consumer electronics and aerospace are increasingly focused on management of supply chain risk. As an optical lens, optical component and assembly manufacturer, Rochester Precision Optics is working with market leaders to manage their risk while reducing their total system cost.
Ray Schmitt joined Rochester Precision Optics as Supply Chain Manager after 25 years in all aspects of manufacturing including Operations Management, Supply Chain, Quality Systems, Sales, Information Technology and Production in polymer optics. Ray is working with customers and vendors to ensure a robust supply chain that exceeds customer expectations.

RPO has been awarded a grant from the Small Business Technology Transfer (STTR) to pursue chalcogenide glass IR optic development for quantum cascade lasers.
RPO, after successful completion of Phase 1 STTR, seeks to develop a fast axis collimating lens for quantum cascade lasers (QCL), which are tunable to emit in the full infrared range. Because primary applications are wide, the lenses must withstand the stress of both continuous wave and pulsed laser emission. Lenses for this application are not known to currently exist, making RPO first in the industry to achieve a working prototype.
Rick Bryant joined Rochester Precision Optics in 2013 after his service in the United States Marine Corps and nearly 20 years as the Director of Visual Augmentation Systems for Naval Special Warfare Development Group. Rick, in collaboration with our VP of Engineering Bob Benson, has been integral to the development and launch of RPO’s CNOD CMOS system and the direction of our night vision R&D. In addition to his R&D leadership, Rick has also led fielding, logistics, and other responsibilities that come with heading advanced programs.
2016 has brought about a lot of change at RPO. We’re pleased to welcome RPO’s new president, Dane Hileman, a sure sign of the investments we are making in people, processes, and technologies to scale from prototype to production of optical components and optical assemblies for our customers.
What’s new? Currently, we are:
- Investing in automation to focus on cultivating high-value technical talent
- Tripling capacity in precision plastic optics – taking on the difficult military applications like prisms and consumer electronics/VR applications that require bi-aspheres and fresnels
- Adding cleanroom capacity—15,000 sq. ft of class 10,000, down to class 100 capable
RPO’s CNOD System is featured in the latest Law Enforcement Technology and Law Enforcement Product News. Because of its true facial identification capability, the CNOD offers superior enhanced performance for SWAT and police departments.
CNOD, CMOS Night Observation Device, enables operators to see in bright sun and low light by combining high definition sight with high contrast and high resolution in a single device. The device is neither an image intensification system nor a thermal system; it is a digital system. CNOD can be deployed in three ways: as a hand held monocular, as a clip-on, in-line weapon sight for use with your day scope or as a stand-alone weapon sight with reticle of choice. Because of its multi-functionality, the CNOD system is unmatched in regards to digital, image intensified night vision and thermal sights in the current market.
Welcome to the Rochester Precision Optics blog. Our optical engineering and lens design team will post regularly with guidance and tips to improve optical system performance and manufacturability. We’ll also share emerging technology and applications in security, life sciences, medical devices, and imaging.
Check back for:
- Ask the engineer
- Optical system case studies
- Precision asphere design and manufacturing tips
- Electro optical assembly tips
Our engineering and manufacturing staff work collaboratively with customers on designs ranging from thermal imaging systems to virtual reality to DNA sequencing. While much of our work is proprietary and confidential, our blog will be used to share techniques and considerations for issues like lightweighting of optical systems, design for manufacturability, and optical system design approaches to cost-effectively scale from prototype to high volume production.
