Reliability that Instruments are Built Around

Semrock filters, manufactured in Rochester, NY, are produced using proprietary hard-sputtered thin-film coating technology that eliminates the environmental degradation, moisture absorption, and spectral drift that limit conventional filter designs.

The result is measurable and guaranteed:

• Greater than 93% passband transmission
• OD 6 out-of-band blocking
• Steep transition edges within 0.5% - 1% of the edge wavelength
• Long-term spectral stability
• Backed by a 10-year product warranty.
• Every unit ships with individually measured spectral data, so instrument designers have verified performance in hand before integration begins.

A Catalog Built for Every Spectral Challenge

Spanning 200 nm to 1,700 nm across UV, visible, and near-infrared wavelengths, our Semrock catalog covers the measurement challenges instrument engineers face most:

• Bandpass filters for fluorophore-specific detection
• Ultrasteep longpass and shortpass edge filters for Raman signal collection within 100 cm-1 of the laser line
• MaxLine^® laser cleanup filters with sub-2 nm bandwidth
• StopLine^® notch filters for simultaneous Stokes and anti-Stokes Raman detection
• VersaChrome^® angle-tunable filters that replace entire filter banks, and dichroic beamsplitters for multi-laser
• Multi-channel imaging architectures

When catalog options are not an exact match, our engineering team designs custom wavelengths, form factors, edge-blackened assemblies, and volume OEM supply programs from the ground up.

Advanced Spectral Precision for High-Stakes Instrumentation

Capturing every photon matters. In fluorescence microscopy, flow cytometry, Raman spectroscopy, and clinical diagnostics, the difference between a decisive result and an ambiguous one often comes down to how precisely an optical filter manages light.

When data quality, patient outcomes, or product quality directly depend on spectral performance, instrument designers cannot afford filters that shift over time, absorb moisture, or require field replacement.

Accelerate Development with SearchLight

Before committing to hardware, instrument development teams can model their complete optical system using SearchLight — Semrock's free browser-based simulation platform.

SearchLight predicts signal brightness, signal-to-noise ratio, fluorescence cross-talk, and autofluorescence contribution for any filter combination, compressing filter selection and system validation from weeks of prototype iteration to hours of simulation.

For OEM development teams under tight time-to-market pressure, it is a direct engineering accelerator at no cost.

Whether selecting from our catalog or engineering a custom solution, Semrock filters provide spectral precision, long-term consistency, and application engineering support that instruments built to last require.

Indispensable Across Demanding Applications

• Life Science Research: BrightLine^® filter sets are factory-recommended for widefield, confocal, TIRF, and super-resolution microscopy platforms worldwide.
• Clinical Diagnostics: Reliable optical performance for qPCR, hematology, and in vitro diagnostic instruments.
• Raman Spectroscopy: RazorEdge^® longpass filters resolve vibrational modes and chemical fingerprints that conventional filters cannot reach.
• Industrial Metrology and Materials Analysis: High-repeatability inspection, measurement, and process control systems.

Flexible OEM Solutions Across Every Stage of Development

Rather than forcing a rigid, one-size-fits-all approach, the IDEX Health & Science team partners with your engineering division to provide flexible options tailored to your project’s maturity:

• Breadboarding: Accelerate your initial path to discovery and rapidly prove your core concept with high-performance optical components, including our Melles Griot XPLAN™ CCG microscope objective lens series, laser light engines, laser autofocus tracking modules and Semrock filters
• Custom Engineering: When off-the-shelf optics introduce bottlenecks like diffraction limits, vignetting, and limited fields of view, we design edge to edge diffraction limited air or water immersion objective lenses with large fields of view, and laser light engines with flat-top 2D and line beam shaping matched to the imaging sensor.
• Manufacturing Scale: Whether you are a startup launching your first platform or an established global OEM shipping thousands of instruments annually, our manufacturing infrastructure scales seamlessly with your demand.

Navigating Complex Architecture Challenges for Multi-Market Optics

When OEM designers build cutting-edge instruments for high-throughput, high-resolution imaging—spanning clinical diagnostics, life sciences, medical technology and industrial inspection, —they face severe architecture challenges. Balancing high resolution against rapid throughput requirements usually forces optical engineers to navigate complex design trade-offs. The IDEX Health & Science team solves these problems by delivering Melles Griot Optical Systems that are tailored specifically to your instrument's unique requirements, matching your exact product lifecycle stage, industry standards, and architectural constraints.

Collaborative Framework and World-Class Infrastructure

Armed with over a century of optical design legacy, massive infrastructure investments, and a specialized team of 140+ engineers, IDEX Health & Science integrates Design for Excellence (DfX) principles directly into your product development process. We work as a direct extension of your internal team, offering weekly design reviews, open black-box modeling data sharing, and exhaustive verification testing.

Operating out of our world-class optical manufacturing centers featuring extensive cleanroom space, we ensure your collection of optics, light engines, autofocus modules, and filters achieve perfect harmony. By matching your development needs with components built for High Throughput and High-Resolution Imaging, IDEX Health & Science helps you optimize operational efficiencies, mitigate supply chain risks, and drive breakthrough industrial and medical discoveries worldwide.

Fluidics capabilities from IDEX Health & Science provide an end-to-end pathway for precision fluid management, supporting life science instrument developers from individual component selection to fully integrated, subassemblies. Managing fluid pathways with total reproducibility is vital for platforms across liquid chromatography (including HPLC ), automated sample preparation, and multi-omics. To meet rigorous demands, our suite of quality components is engineered to function seamlessly. Our bioinert products include custom valves, high-efficiency degassers, precision pumps, sensors, probes, high-purity tubing (PFA, FEP, PEEK, and medical-device configurations), column hardware, and low-dead-volume fluidic connections like Luer and HPLC fittings.

However, the true strength of our fluidics portfolio lies in the ability to integrate these parts into full fluidic subsystems. IDEX Health & Science reduces the physical footprint of an instrument, eliminates complex tubing configurations, and reduces leakage points. These custom fluidic solutions are optimized for critical instrument operations such as multi-reagent selection, automated reagent preparation, precise routing, and fluidic control. To minimize integration risks for our partners, every single integrated subsystem is built, engineered, and validated as a single functional unit using advanced testing capabilities. Our experts assess flow paths, pressure behaviors, and fluidic stability, supplying reliable validation data before the subsystem ever reaches the assembly line.

This co-development approach reduces overall engineering complexity, keeps development costs competitive, and guarantees the lifetime and serviceability required in biotechnology applications. We also reduce supply chain uncertainty, optimize operational efficiency to drive your breakthroughs in clinical discoveries.
