BrightLine® single-band multi-exciter filter set, optimized for FURA2 and other like fluorophores

Semrock Part Number: FURA2-C-U03

IDEX Part Number: S-000778  /

This four-filter BrightLine fluorescence set is specially designed to achieve high-performance fast ratiometric imaging of Ca2+ using Fura-2 as an indicator. The carefully optimized excitation filters provide superb balance of free and saturated Ca2+ signals, while minimizing the crosstalk and noise, resulting in the most accurate ratiometric measurements. The high signal throughput of the filter set permits reliable Fura-2 (Ca2+) measurements, even when using light sources of relatively limited ultraviolet output. Independent laboratories have measured this set to have 2-4X the free and saturated signals as compared with filters from the leading competitor.

Optical Specifications Value
Blocking BrightLine filters have blocking far exceeding OD 6 as needed to ensure a black background, even when using modern low-noise CCD cameras. The blocking is optimized for microscopy applications using our exclusive SpecMakerâ„¢ fluorescence filter design.
General Filter Specifications Value
Optical Damage Rating Testing has proven to show no signs of degradation when exposed to at least 6.0 W of power from an unfiltered xenon arc lamp over a 25 mm diameter (corresponding to 1.2 W/cm2) for over 500 hours.
Microscope Compatibility BrightLine filters are available to fit Leica, Nikon, Olympus, Zeiss, and Aperio microscopes.

Cleaning Optical FiltersInstructions for cleaning hard coated optical filters
Filter ReliabilityCompares the performance and reliability of hard coated filters to traditional soft-coated filters and provides information about the testing standards for Semrock filters
Working with Optical Density Tables to describe the relationship between OD and transmission with tips for quickly calculating OD
What is Pixel Shift, and how does the Semrock ZERO option help? Why Pixel Shift degrades multicolor fluorescence imaging performance, and how the ZERO™ option mitigates this for Avant and BrightLine filter sets.
This set is delivered unmounted and fits Olympus OFF cubes which is compatible with the BX3 (BX53, BX63) and IX3 Series (IX53, IX73, IX83) of Evident Scientific (Olympus) microscopes.
Optimized – Filter set is specifically optimized for that fluorophore.
Compatible – Should result in nearly ideal performance in most situations.
Acceptable – Actual performance is dependent on specific experimental conditions.
