Meet us at Photonics West 2025

We will be joining the and Photonics West 2025 exhibition from January 28th to January 30th.

Join us at SPIE Photonics West 2025, the world’s leading event for photonics, lasers, and optoelectronics. From January 28–30 at the Moscone Center in San Francisco, you’ll find us at booth 3321, showcasing our latest advancements in optical filters.

We specialize in the design and manufacturing of custom optical filters, including bandpass, edge, blocking, dichroic, and linear variable filters. Leveraging advanced design and deposition control software, we ensure a seamless transition from prototypes to volume production.

By maintaining an open dialogue with our customers about their requirements and the available technical possibilities, we consistently collaborate to deliver the best possible solutions

Explore Our Advanced Multi Bandpass Filters

Multi-bandpass filters are well suited for fluorescence spectroscopy instruments that need to work with multiple excitation wavelengths and/or multiple emission wavelengths.

We manufacture double, triple, and quad bandpass filters with high pass-band transmission and deep out-of-band blocking.

In combination with a range of LEDs, these filters are ideal for building fast and complex optical systems with no moving parts.

Revolutionizing Point-of-Care Diagnostics with Precision Fluorescence Filters

Experience the power of our fluorescence filters, designed specifically for point-of-care applications. These high-performance filters deliver unmatched precision, enabling rapid and reliable diagnostics when it matters most.

Discover how our cutting-edge technology is advancing healthcare by providing the accuracy and efficiency needed for critical diagnostic workflows.

Endless possibilities with Variable Filters

Continuously Variable Filters (CVFs) – also known as Linear Variable Filters – from Delta Optical Thin Film is wedged filters, whose spectral properties vary continuously along one dimension of the filter.

A single CVF for example can replace a large number of fixed filters or a grating based monochromator in an instrument. It is possible to adjust the center or edge wavelength by sliding the filter or rotating it.

CVFs are also ideally suited for order sorting in diode-array-based spectrometers.

Setting the Standard in Fluorescence Filters

At Photonics West 2025, we’re spotlighting our industry-leading fluorescence filters, crafted for unparalleled performance in demanding applications. Designed with precision and innovation, these filters enhance fluorescence detection, delivering superior signal-to-noise ratios and optimal transmission.
