Meet us at Laser World of Photonics 2025

We will be joining the Laser World of Photonics 2025 June 24th to 27th in Munich.

Visit us at booth B1.255, where we will showcase a variety of our high-performance interference filters for advanced applications.

You will have the chance to speak directly with our CEO, sales directors, and members of our R&D team to discuss your application needs and explore how our optical filter technologies can support your optical projects.

We warmly invite you to contact us to schedule a meeting in advance to make the most of your visit. Below, you can also explore a selection of our latest innovative products, designed and manufactured to meet demanding optical requirements.

Let’s connect in Munich and shape the future of photonics together!

Presentation: PARMS-Enabled Breakthroughs in Advanced Optical Filter Design

Quad-band emission filter and beamsplitter

The commercial availability of Light Emitting Diodes at almost any wavelength combined with Multi-Bandpass Filters have enabled ultrafast switching between different wavelengths in fluorescence microscopy.

Our multi-band filter products – a quad-band emission filter and a quad-band dichroic beamsplitter – are excellent examples of the kind of filters that we can design and manufacture for our OEM-customers.

Fluorescence filter set with deep blocking

Our new fluorescence filters feature best-in-class out-of-band blocking. These filters deliver exceptional performance, minimizing background interference and cross-talk enabling our customers to build even better products.

Improved Linear Variable Filters

At Delta Optical Thin Film, we have been at the forefront of developing and manufacturing Linear Variable Filters for decades. Our commitment to innovation drives us to continuously enhance the capabilities of our filters.

Recently, we achieved significant improvements in our Linear Variable filters, reducing passband ripple and increasing UV-throughput for better performance.

Beamsplitter with very steep edge

Thanks to its extremely steep transition between the reflection and transmission bands, this new dichroic filter allows you to either combine two light sources with a very small wavelength difference or work with fluorophores that have minimal wavelength separation between their excitation and emission bands.
