About our Products
Highest quality dyes
and specialty chemicals
Exciton continues its more than 40 years history in supplying the highest quality laser dyes, absorber dyes, and specialty chemicals.
We continuously strive to bring new dyes to market across spectral regions from the infrared to the ultraviolet, and we introduce the latest science in the form of new dyes with superior performance.
For ease of reference, the number in the dye name indicates the approximate peak lasing or absorption wavelength.
Laser & Fluorescent Dyes
Dyes and dye lasers still provide the unique combinations of power, pulse length, wavelength and reliability that are required for many applications ranging from materials research to medicine.
Our products are used in research laboratories and medical offices around the world.
Absorber Dyes
Selective light filtration (absorption) is key to the performance of many optical products from ophthalmic lenses for laser protection and enhanced contrast, to displays, to filters for digital sensors (cameras).
Our non-fluorescent narrow-band visible and infrared dyes are incorporated into products that are sold globally.
Specialty Chemical
Our niche offering in specialty chemicals includes a wide variety of structures and functions derived from our dye chemistry work. For example, we offer dyes for photolithography (triplet sensitizers), biological probes (including, in some cases specific isomers), porphine (the most basic porphyrin), and other specialty chemicals upon request. Please contact us for your custom dye-related requirements.

Technologies
Exciton excels in the production
of high purity dyes
For over 4 decades, Exciton has invested in complementary technologies of highly fluorescent dyes, including laser dyes, and selective absorber dyes, including both visible and infrared absorbing dyes for optical filters, from laser protective eyewear to digital camera filters.
Exciton excels in the production of high purity dyes, which is critical in laser dyes for maximizing dye laser output, in sensitizing dyes for photolithographic applications, and in absorbing dyes where impurities can lead to losses in luminous transmission or may introduce haze or scattering in laser filters.
Exciton carries out a wide range of new product and new process development activities to support its broad customer base. In addition, Exciton customizes and formulates dyes using a unique combination of chemistry and optical engineering capabilities. For example, Exciton manufactures high thermal stability dyes for polycarbonate molders who produce the highest optical quality filters.
Exciton's new, modern facility near Columbus, Ohio includes both glass and stainless steel reactors for the production of dye intermediates and dyes, as well as associated products.
