TECHNICAL NOTE<br />
You Can Clean <strong>Semrock</strong> Optical Filters!<br />
<strong>Semrock</strong> manufactures the most durable optical filters available.<br />
However, it is important to note that while all optical components<br />
should be handled with care, soft-coated filters are especially<br />
susceptible to damage by handling and cleaning. Fortunately,<br />
<strong>Semrock</strong> supplies only hard-coated filters, so all of <strong>Semrock</strong>’s filters<br />
may be readily cleaned using the following recommended method.<br />
The following are recommended to properly clean your filters:<br />
• Unpowdered laboratory gloves – prevent finger oils from<br />
contaminating the glass and keep solvents from contacting skin;<br />
• Eye protection – critical for avoiding getting any solvent in your eyes;<br />
• Compressed air – clean, filtered laboratory compressed nitrogen<br />
or air is ideal, but “canned” compressed air or even a rubber “bulb<br />
blower” in a relatively clean environment is acceptable;<br />
• Lint-free swab – cotton-based swabs work best;<br />
• Lens cleaning tissue – lint-free tissue paper is also acceptable;<br />
• Cleaning solvent – we recommend Isopropyl Alcohol (IPA)<br />
and/or Acetone. Care should be taken when handling these<br />
solvents, especially to avoid ingestion.<br />
1. Blow off contaminants. Many contaminants are loosely attached to<br />
the surface and can be blown off. Using laboratory gloves, hold the<br />
filter in one hand and aim the air stream away from the filter. Start<br />
the air stream using a moderate air flow. Maintaining an oblique<br />
angle to the part – never blow straight on the filter surface – now<br />
bring the air stream to the filter, and slowly move it across the<br />
surface. Repeat until no more loose particles are disappearing.<br />
2. Clean filter. If dust or debris remains, it is probably “stuck” to<br />
the surface and must be removed with mechanical force and/or<br />
chemical action. Create a firm but “pointy” tip with the lint-free<br />
wipe or lens tissue by folding it multiple times into a triangular<br />
shape or wrapping it around a swab. Lint-free swabs may also be<br />
used directly in place of a folded wipe. Moisten the wipe or swab<br />
with either IPA or Acetone, but avoid too much excess solvent.<br />
The key to cleaning<br />
the optic is to maintain<br />
one continuous motion<br />
at as constant a speed<br />
as possible. Some<br />
people prefer to<br />
clean using a “figure<br />
8” pattern while others<br />
choose to start in the<br />
center of the part and wipe<br />
outward in a spiral pattern.<br />
Do not stop the wipe on<br />
the surface – keep the wipe<br />
moving at a constant speed, lifting the moving wipe off the part<br />
when you reach the end of the pattern.<br />
3. Inspect filter. Use a room light or any bright light source to<br />
inspect the optic to ensure that it is clean. Tip, tilt, and rotate<br />
the optic while viewing it as close to your eye as you can focus. If<br />
contamination remains, start with a brand new wipe or swab and<br />
repeat step 2 above.<br />
4. Repeat steps 1 – 3 for the other side of the filter if<br />
contamination exists.<br />
Precautions for Edge Blackened Filters<br />
For <strong>Semrock</strong> edge blackened filters, the above procedures<br />
can be used with the following precautions.<br />
• Only IPA or water based cleaning solutions can be used.<br />
• Acetone, Methanol, and other chemical solutions should be<br />
avoided as they will damage the edge blackening material.<br />
• Aggressive wiping of the blackened edge should be avoided.<br />
Note: IPA and Acetone each have pros and cons, so choose the solvent that<br />
works best for you after trying both.<br />

Filters<br />
SearchLight allows fluorescence microscope users and optical instrument designers to predetermine the optimal fluorophore,<br />
light source, detector, and optical filter combinations for their microscope or system. By removing the guesswork and hours of<br />
searching multiple sources for spectral data, SearchLight users will be able to eliminate trial-and-error headaches and work more<br />
efficiently. Users may select from an extensive collection of preloaded spectra or upload their own spectral data in this free and<br />
openly accessible tool. Users can also save and share their data securely.<br />
Share: The share feature within SearchLight<br />
enables collaboration across researchers,<br />
engineers, companies and institutions by<br />
creating a unique URL link to the session which<br />
can be emailed to a colleague or collaborator.<br />
