Bandpass Filters are commonly used to isolate narrow emission or absorption features from a broad spectral range within analysis instrumentation. Multiple filters are often used within a selction mechanism such as a filter wheel. These filters are traditionally manufactured using cemented structures utilising soft coatings. Envin offers such filters in a wide range of wavelengths […]
Filters for use in Fluorescence applications are a speciality of the company and include both Excitation and Emission products. Designs for many different Fluorophores are available including standards such as Ethydium Bromide and for more demanding applications such as ‘Cy dyes’ or ‘Qdots’. Filters with steep transition edges and high blocking levels (OD6 +) are […]
