Product Description
1. Brief Description:
Optical fluorescence filters are the essential components for most of the life science and biochemical analyzer instrument. As the requirement of precise diagnose and analyze, it requires narrow bandwidth which is usually 8nm and 10nm.Light outside the interested area is blocked to above OD4. Wavelength for such kind of application is from 200nm to 1100nm.
2. Application:
fluorescence microscopy, PCR analyzer, microplate reader, raman microscopy, cell counters, flow cytometry, fluorometer, surgical devices and other application which needs high content analysis imaging system.
3. Advantage of Optolong Fluorescence Filter
(1) Multi cavity deposition makes thin film layers to be more than 300.
(2) Durable hard coating film layers.
(3) More than OD7 blocking depth on one single substrate.
(4) Transmission above 90%.
(5) Bandwidth narrow to 3nm.
(6) Unique design to control rectangularity, overlap.
(7) Wide angle of incidence change.
FAQ
1. What kind of fluorescence filter you can provide? Do you offer Dual-Band Filter and Triple-Band Filter?
Optolong provide single-band, dual-band and triple-band fluorescence filter for you to choose.
Single-Band Filter:BFP | CFP | GFP |YFP | DAPI |FITC | TRITC |Texas Red | mCherry | Cy3 | Cy5 | Cy5.5 | ICG | FISH Aqua | FISH Green | FISH Red | FISH Orange
Dual-Band Filter:Dual-band Green | Orange-Red H
Triple-Band Filter:DAPI-FITC-TRITC | DAPI-FITC-Texas Red
2. Can you offer long/ short pass filters and high/low pass filters besides the band-pass filers?
Yes, we can. Considering the image quality, however, we recommend the band-pass filters instead of the long pass filters.
3. Do you accept OEM order for fluorescence filter? What is the size and blocking range you can do?
Yes, we can do the OEM order for fluorescence filter. We can coat the single glass above 10000nm thickness and with blocking range above OD5.
Usually the size range for fluorescence filter is ∮3-∮77 for circle and 2.8mmx2.8mm-81mmx81mm for square. We have provided the products with size of Dia50mm, Dia25mm, Dia22mm, Dia18mm, Dia12.5mm and Dia8mm to our customers.
4. Do you provide cube for fluorescence filter set? Dose the price you quoted include the cube?
The cube we provide is U-MF2, which can be used in Olympus AX,BX,IX series.
The price we quoted don't include the cube. For the cube price, please contact our sales people.
5. What specification should I provide for OEM order of fluorescence filter?
The size, spectrum specification(like wavelength, blocking range and so on), application, quantity and other specific requirements.
6.What the advantage you have compare with other competitor?
We offer the much better price with almost the same quality. Please contact us for the fluorescence image that compare with one of international famous brand which tested by our customer.
7. What is your lead time?
Standard fluorescence filter can be sent the same day payment received. Other stock filters with different size can be sent within 7 days after payment confirmed. Normal OEM orders can be shipped within 15 days. Special OEM orders shipment time depends.
8. How is the payment terms of Optolong?
T/T (100% payment in advance or 30% in advance and 70% in balance )and paypal are accepted.
