Filter wheels hold and position multiple filters for various imaging applications such as machine vision and spectrophotometry. Search by Specification | Learn More
Optical diffusers scatter incident light, thereby reducing the sensitivity of a detection system to slight positional or angle changes in an incoming beam. Search by Specification | Learn More
Opacity sensors and instruments measure the amount of light transmitted through a sample. Search by Specification | Learn More
Industrial air filters reduce the number of particles in the air that passes through them. Search by Specification | Learn More
Display filters and films are designed to filter, enhanced and/or protect monitors or flat panel displays (FPD). Search by Specification | Learn More
Laboratory filters are used to remove particulates from samples in laboratory-scale applications. They consist of a filter medium and housing or holder that constrains and supports the filter media in the sample’s path. Search by Specification | Learn More
Color filters include a wide range of filter types that are distinguished by their specific color spectrums and wavelengths, as well as their Schott glass compositions. Search by Specification | Learn More
Density and specific gravity instruments are meters used to determine density and specific gravity. Search by Specification | Learn More
High-efficiency particulate air (HEPA) filters and ultra-low particulate air (ULPA) filters are designed to screen particles larger than 0.3 µm Search by Specification | Learn More
RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters. Search by Specification | Learn More
Industrial filtration equipment is used to filter, thicken or clarify a mixture of different elements. Search by Specification | Learn More
Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI. Search by Specification | Learn More
Machining oil, cutting fluid and coolant filters are industrial filtration products used in metal processing applications to improve performance, product quality, and equipment life (i.e., maintenance schedule, repairs). Search by Specification | Learn More
