Controlling Cost for Large Optics

By Ross Team | Oct 20, 2017 7:30:51 AM

Generally speaking, a "large" optic is anything with dimensions exceeding 10 cm. Designing a large optical system is not intrinsically harder than designing a smaller system, but the stakes are higher. The classic example of a large optics project gone wrong is the Hubble Space Telescope, in which an error in metrology resulted in a mirror that was made "exactly wrong" to very high precision.

Keep in mind that, when designing a system that includes large optical elements, the effects of the usual cost factors increase and some new factors appear. The following design points will help.

How I Spent My Summer Vacation: Optics + Photonics 2017

By Charlie Metzger | Sep 28, 2017 8:30:00 AM

I attend the SPIE Optics + Photonics conference every year, mostly just to walk the show. Compared to other shows, O+P is a pretty laid back event, perhaps because it is at the end of summer or perhaps because it is in Southern California. Because it is a slower conference, you really need to plan ahead if you want to get the most out of it.

Optics Provide a High-Res Look at a Galaxy Far, Far Away

Have you ever tried to take a picture of a bright full moon or a star-filled sky, only to be disappointed when virtually nothing shows up on your phone screen? The distance and brightness of these objects make it nearly impossible to get a sharp image—and that’s just in our own galaxy.

Offshore Sourcing: Helping Customers Bail Out from Bad Overseas Vendors

By Charlie Metzger | Aug 31, 2017 9:05:00 AM

There's nothing wrong with sourcing optical parts from overseas. We frequently do it ourselves. However, working with vendors on another continent has its risks, and when things go wrong, they tend to go really wrong. Problems include:

Three Opto-Mechanical Design Challenges

By Ross Team | Jul 20, 2017 9:43:00 AM

Opto-mechanics refers to the mechanical design of optical systems. Opto-mechanical design is sometimes dismissed as little more than "wrapping metal" around the optics, but that perspective is detrimental to building the best operating optical instrument.

Improving Delivery of Optics through Kanban

By Ross Team | Jul 7, 2017 8:50:00 AM

Kanban, a method used to visualize and optimize workflows, has long been a key part of Ross' processes. Kanban has 5 core properties: (1) visualize workflow, (2) limit work-in-progress, (3) manage flow, (4) make process policies explicit, and (5) improve collaboratively. At Ross, we help you with 3–5 so that you can focus on 1 and 2. When managing and delivering optics inventory to customers, we aim to:

Going Off Map: 5 Non-Optical Considerations for Optical Materials Discovery

By Lisa Yang | Jun 8, 2017 9:00:00 AM

A “glass map” is often the first tool in optical design. The map is a quick way to determine a suitable range of optical materials in terms of refractive index (n) and dispersion (“Abbe number”, “nu number”, or “V-number”). Finding the ideal region on the glass map is only the first step, though. Several “non-optical” factors must be balanced to determine which materials are most promising. We’ll consider 5 of the most important.
