Filter Sets

Optimized filter sets for the Co-Lase laser combinations provide detection for fluorochromes and dyes using both lasers simultaneously and are specially designed to block unwanted light from the lasers themselves.  Included with these filter sets are Propel Labs’ improved dichroic and bandpass holders.

Filter Holders

Propel Labs’ optimized filter holders are made of anodized aluminum. The holders use screw-in retaining rings (rather than press in) and the dichroic holders use tension bars (rather than O-rings) for improved alignment and stability

“I’m pretty sure I saw an immediate improvement in alignment after popping this dichroic holder from Propel Labs into my 561nm path. If you have a MoFlo and are sick of the plastic holders that never fit quite right due to those silly rubber O-rings then you should definitely check these out. First of all, they fit nicely. Secondly, they give much better control of actual position, and lastly they stay where you put then. I’m definitely going to outfit our MoFlo with these dichroic holders (they have band pass holders as well). We actually do a lot of filter swapping on the MoFlo compared to our other instruments mostly because we can. But I’m always second guessing the dichroic alignment. We play some silly games like propping one end of the holder up slightly, or pushing just past the optimal alignment point in hopes that the rubber O-ring will pull it back ever so slightly into alignment.”

“We installed the new filter holders on our MoFlo. Due to the friction fingers designed to keep the assembly from rotating or popping up I almost never have to adjust them day-to-day and when I do, they stay where I want them to be. I prefer this design over the rubber O-rings. This makes alignment and troubleshooting much easier. Another benefit is the screw type system used to secure the filters to the holders. Once they are screwed in they stay in, which prevents filters from falling out and sometimes cracking on the floor.”
