Semrock’s industry leading laser dichroic beamsplitters just got flatter. We’re setting a new standard for Super-resolution / TIRF microscopy with λ/5 P-V RWE on our new 3 mm thick dichroics and 1λ P-V RWE on our improved 1 mm dichroics. Each one comes with our Semrock guaranteed steepest edges, short wavelength reflectivity down to 350 nm, and long wavelength transmission optimized out to 1200 nm or 1600 nm.

Dr. Raimund J. Ober, renowned co-founder of the Ward Ober Lab at Texas A&M University, were early innovators in building systems that provide microscopic imaging that is not constrained to a single focal plane. It's termed Multifocal Plane Microscopy or MUM. Learn how optical filters play an important role in this application.

LED-based light engines are steadily replacing traditional mercury, metal-halide and xenon light sources in fluorescence microscopy. As the spectral output of LED-based light sources differs from that of traditional sources, optical filter sets which were designed to take advantage of the peaks of the traditional sources, may now be sub-optimal for use with LED-based light engines. Semrock is now offering fourteen sets in single-band, full Pinkel & Sedat multiband configurations designed to be spectrally aligned with the excitation output of the most popular LED light engines on the market today.
