What Spectrolight does
Spectrolight Inc. is a privately held South Korean optical technology company, headquartered at 7-16 Naseongnam-ro, Sejong-si, that designs and manufactures photonic instruments for spectroscopy and spectral imaging. Its core offering is the Flexible Wavelength Selector (FWS) family of tunable bandpass filters built on a proprietary TwinFilm™ technology, which combines grating-monochromator wavelength selection with circular-aperture bandpass filter imaging; the resulting products cover center wavelengths from 255–1700 nm with tunable bandwidths of 2–20 nm FWHM, >75% transmission efficiency, and out-of-band blocking of OD 5–10. The catalog extends to light sources (Energetiq LDLS covering 190–2500 nm, SL-Pico supercontinuum lasers, tunable light sources, tungsten-halogen and plasma lamps), hyperspectral imaging systems and cameras, and ancillary optical components (spectrometers, light aligners, optical fibers, mounting bases).
The company sells direct to end users worldwide via its own e-commerce storefront, shipping from South Korea; pricing is one-time hardware purchase, ranging from roughly $1,400–$1,500 for a CenterLine20 model, $3,200–$4,600 for CenterLine10 configurations, and additional accessories from $65–$180, with custom (CWS) units quote-based and shipped within 72 hours. Target buyers are research institutions and university laboratories (physics, optics, chemistry, quantum), life sciences and biotechnology (fluorescence imaging, microscopy, drug discovery, optogenetics), materials science labs, industrial metrology and quality control teams, and medical/environmental monitoring applications — a horizontal segmentation driven primarily by use case rather than by a single named vertical. There are no disclosed funding rounds, no reported revenue, no headcount data beyond an 11–50 employee band, no institutional investors, and a co-located affiliation with iiSM Inc. at the same address whose relationship is unconfirmed.
