The Importance of Designing for Optical Assembly

By Damon Diehl | May 15, 2018 10:48:00 AM

The optical assembly process is often treated as an afterthought of the design process; however, once a product has gone into production, assembly becomes a dominant cost. Designing for ease of assembly becomes a considerable cost-saver in the long run. Below we offer three important points to consider as you develop a product.

Warming Up: Three Hot Markets for the Infrared Optical Industry

By Ross Team | Feb 20, 2018 12:07:36 PM

Demand for infrared optical elements has extended beyond just lens assemblies and hot/cold mirrors. Specifically, there is growing interest across the optical industry for bandpass filters, achromats, athermal elements, and polarizing waveplates. The demand spans all IR wavelength bands—near IR (0.75 µm to 1.4 µm), short-wavelength IR (1.4 µm to 3 µm), mid-wavelength IR (3 µm to 8 µm), and long-wavelength IR (8 µm to 15 µm). Advances in sensor and source technology, as well as a changing marketplace, are driving this growth. Demand from three industries stands out as particularly noteworthy:

FAQ: Tolerances & Tips for Super-Polished Optics

By Ross Team | Jan 18, 2018 1:05:00 PM

What is super-polishing? 

Super-polishing is a new classification for optical surface quality, sometimes referred to as "atomically smooth." By this we mean surface roughness features that can be measured in Angstroms, which are ten times smaller than nanometers. A single hydrogen atom is roughly 1 Å in diameter, so super-polishing really is “atomic.” By comparison, a λ/100 specification is 6 nm.

Cleaning Optical Mirrors vs. Lenses: 3 Key Differences

By Ross Team | Jan 11, 2018 9:04:00 AM

The recommended procedures for cleaning optics are largely the same whether you are working with lenses or mirrors. The typical cleaning process involves first blowing dust and dirt off the optical component with pressurized air, then using the drag method to slowly move moistened lens paper across the optical surface. We’ve previously shared tips for avoiding damage during optical cleaning. However, a few key differences make mirrors more susceptible to accidental damage.
