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.

Providing Optical Design Support During the Contract Development Process

By Ross Team | Dec 19, 2017 8:45:00 AM

At Ross Optical, we take pride in our reputation for outstanding customer support. A big reason for our customers' satisfaction is how we handle customers before they are our customers. Many optical suppliers require contracts and commitments before they will help a customer with design issues. At Ross, we think that's backward. Getting to the best design can take some time, and we prefer to help our customers overcome those design hurdles before committing to an order. The design collaboration process varies from customer to customer, but it typically goes something like this:

Three Examples of Using Cylinder Optics for Beam Shaping

By Lisa Yang | Nov 15, 2017 9:15:00 AM

Unlike a conventional spherical lens, a "cylinder lens" has curvature along only one axis, as shown in the first figure. Cylinder lenses are useful in applications where light needs to be manipulated in only one direction. The example shown is a plano-convex positive lens, which brings parallel rays to a line focus.
