Core Components
Choose individual filters and optics to build or customize your system:
Single Bandpass Filters — Clean excitation or detection with tight passbands.
Multiband Bandpass Filters — Faster acquisitions and fixed registration across multiple colors.
Dichroic Beamsplitters — Separate excitation and emission with durable sputtered coatings.
Longpass Filters — Pass longer wavelengths to capture emission tails or block stray excitation.
Shortpass Filters — Cut off red/IR while passing shorter wavelengths for clean-up.
Notch Rejection Filters — Deep line blocking for laser suppression and Raman workflows.
Neutral Density Filters — Control intensity without altering spectral shape.
Reflective Mirrors — Robust mirrors for beam steering and alignment.
Built for Research Reliability
Our hard-sputtered coatings are virtually impervious to degradation from the intense illumination and environmental stresses common in microscopy labs. This ensures a filter's spectral performance will not drift over time, guaranteeing that data collected at the beginning of a multi-year study is directly comparable to data collected at its conclusion.
As an ISO-certified company, we adhere to strict quality assurance procedures and stand behind this commitment with an industry-leading warranty—our assurance of long-term experimental stability and reproducibility.
