Welcome to the Fourth Issue of our Wavelengths Newsletter in 2011. In this issue we are excited to continue our discussion on overcoming pixel shift and registration problems during multicolor fluorescence imaging.
We also have an interview with Dr. Eric Potma, Assoc. Professor at UC Irvine, who’s research interests include quantitative imaging of biopolymers using Nonlinear Optical Microscopy and also characterizing the nonlinear optical properties of nanostructures.
For smartphone and tablet users, we recently launched our mobile website: m.semrock.com. Currently, the site has all of our technical information available. Now you can easily read up on angle of incidence or cone half angle while enjoying a latte at the coffee shop!
We would like this newsletter to be a collaborative project with the microscope community at large. We invite and encourage you to send us your ideas, tips, questions, ideas for improving the newsletter, articles and anything else you think we should know or share. Enjoy.
- Nick George, Director of Product Marketing

This question comes up occasionally. The Rayleigh Range is the distance from the beam waist (smallest focused spot) to the point where the waist has increased by a factor of √2. Images focused within one Rayleigh Range of the waist appear to be in focus. When working with gaussian beams (often an excellent model for a laser beam), the depth of focus is quantified by the Rayleigh Range. In order for images to remain in focus, reflecting filters (dichroic beamsplitters, for example) need to be flat enough to cause the reflected beam to shift less than one Rayleigh Range.
See webpage for more information on the different levels of flatness of our dichroics.
