What's your favorite part of your job at Ross Optical?
My favorite part is to work both directly with customers and our own employees.
By talking to customers, it gives me a chance to know what kind of products the optics are used to make, and what the expectation will be of us as a vendor. Knowing their end products also makes me aware of the type of specification that the optics need. Sometimes I can make recommendations of other optics that fits their needs better.
Also, when talking to customers, I know what kind of price range and lead time fits their project; in cases where they prefer to have the parts sooner than the usual lead time, I can relay the info to our team, and they expedite the work.
What kinds of projects are you working on right now?
I am reverse engineering a projection lens assembly. My next project is also in reverse engineering: microscope lenses including the video adaptor lens and the eyepiece lenses.
What are some questions customers most frequently ask?
As a sales person, usually people ask me: "Can you make the lead time shorter?" "Can you give me a lower price?" Our team works with customers to make the answer "yes" as often as possible.
On technical questions, sometimes I am asked if the V-coating is good for only ONE wavelength. The answer is “no” – we can coat for a range of wavelengths.
What's the most interesting problem you've helped solve recently?
One customer originally planned to a use molded aspheric lens. Not only is there a lead time to manufacture this lens, but there is also a sizable tooling cost involved. Looking at the specs of their lenses, I suggested using a lens we have in stock. The lens worked in their system, and I got a happy customer.
Another customer sent me a lens assembly with a couple of lenses inside the lens tube. When I found out that it is for a light collimating purpose, I recommended using one of our catalog lenses. It saved them financially by not needing the assembly, and it used only one lens instead of a few.
