Dear Madam/Sir I want to perform some preliminary fluorescence tests for a project of ours. I am interested in buying one of the following emission filters MF525-39: GFP MF530-43: FITC I noticed from your records that the outer diameter of the filter is 25 mm. In our system we need a filter with outer diameter 17 mm. The filter could be bare glass without an outer support ring. Is it possible to have one of the above mentioned filters in this form? What would be the cost? Best regards, Dimosthenis Stamopoulos

Response from Buki at Thorlabs to Thank you for your interest in our imaging dichroic filters. Testing has shown no signs of degradation when exposed to at least 6 W of power from an unfiltered xenon arc lamp over a 25 mm diameter (corresponding to 1.2 W/cm2) for over 500 hours. Please contact TechSupport@thorlabs.com if you have any questions.

Can you please provide laser damage threshold ratings for the dichroic filters?

jjurado (posted 2011-03-22 16:05:00.0)

Response from Javier at Thorlabs to flickingerd: Thank you for your feedback. Our filters follow that same convention as that of Semrock's. The arrow points to the recommended direction of light propagation. The reason for this is although the filter will function with either side facing the source, it is recommended to place the coated side toward the source. This will minimize any thermal effects or possible thermal damage that blocking intense out-of-band radiation might cause due to absorption by the substrate or colored glass filter layers.

A response from Laurie at Thorlabs to flickingerd: As a follow-up to the response you received earlier today from Javier in our technical support group, I wanted to also reach out to you to thank you for your feedback. We have updated our web presentation to provide information about what the arrow on these optic mounts indicates. As a further step, we have made a list of other web pages on our site that need some attention for similar reasons. In the coming days, we will be updating those pages to clarify our engravings so that our customers can efficiently find the information they need to use our products effectively. Again, thank you for taking the time to drop us a note with a suggestion for improvement.

flickingerd (posted 2011-03-21 14:29:07.0)

I couldnt find info on proper filter orientation. There are arrows on the filters, but Ive seen different conventions on what these mean (Chroma says point arrow towards specimen for emission filters, yet Semrock convention is always point arrow in direction of light propagation, I think). How about your filters? This should be in "Tutorial" section, Id think. Please contact me with proper orientation rules. (Although Im still not sure exactly why this matters...I guess I can think of some minor reasons...)

A response from Adam at Thorlabs to pludowise: I believe we should be able to offer this item as a custom option. I would like to contact you directly to get more information about your application, the quantity necessary, and the exact size of the optic.

pludowise (posted 2010-02-18 00:01:38.0)

I am interested in finding a dichroic filter similar to MDF-TXRED, but shifted to loger wavelengths. Specifically, I need a dichroic for a Cy5 dye, which needs to transmit at 640 nm, and reflect at 690 nm. I also need this in a 1 mm thickness mounted at 45 deg AOI. Thank you.

These excitation fluorescence imaging filters are specifically designed to be used in microscopy and imaging applications. Each Ø25 mm filter is mounted in a 5 mm thick black anodized housing. The housing has an arrow engraved on it that points in the recommended light propagation direction.

These filters provide excellent transmission of the desired excitation wavelength (>90%), with a sharp spectral cutoff and low transmission at other wavelengths (<0.001%). Click on the More Info Icon icons above to view product-specific transmission data. For additional fluorophore compatability, please see the Fluorophores tab.

Thorlabs' Dichroic Filters are designed to separate light of different wavelengths. When light is incident on the filter at a 45° angle with respect to the normal, the excitation light and its associated back reflection are reflected while the longer wavelength fluorescence signal is transmitted. These filters are unmounted, but are marked by a dash to indicate the coated side of the filter, which light should be incident on. Each filter is 25.0 mm x 36.0 mm. If your application would benefit from a round, mounted dichroic filter, consider our round Dichroic Filters. Click on the icons above to view product-specific transmission data.
