Semrock BrightLine Bandpass Filters

IDEX Health & Science stocks an exceptional range of Semrock high-performance, high reliability, individual fluroescence bandpass filters that have been optimised for use in a variety of fluorescence instruments.

These filters all utilise Semrock's patented single-substrate construction for exceptional durability and permanent, "no burn out" performance. The substate is a high-optical-quality and low autofluorescence glass. The size refers to the outer dimensions of the filter. Unless otherwise noted, all filters are housed in a standard 25mm diameter round, black-anodised aluminium ring, with a clear aperture of at least 21mm.

New May 2025 - Introducing BrightLine 2.0 and BrightLine Basic. IDEX have meticulously redesigned and introduced new BrightLine catalog filters, aligning individual filter spectral specifications and production processes with standardised family set requirements. This strategic redesign allows us to offer these high-quality, reliable sets at an unprecedented price point without compromising quality or performance. For cost-conscious customers, the redesigned BrightLine Basic Optical Filter Sets offer exceptional value. This new product family features individual filters designed to standardised requirements with relaxed spectral and cosmetic specifications compared to the BrightLine catalog filters. These filters are not simply "lesser" versions of our premium offerings. Instead, they are specifically engineered to meet the needs of applications where stringent specifications are less critical. By relaxing certain requirements, we've been able to offer BrightLine Basic sets at an incredibly competitive price point. Read more.
