Filters for SPECTRA X light engines®

Lumencor’s SPECTRA X light engine provides six independently controllable sources that span the visible spectrum from 380-680 nm. Each SPECTRA X light engine comes equipped with a set of seven optical bandpass filters, providing the capacity to refine and tune the source outputs to meet experimental requirements. The filters are installed in removable paddles, allowing users complete flexibility in terms of purchasing and using filters in addition to the initially installed set. One filter is applied to each of the six solid state-light sources (violet, blue, cyan, teal, green+yellow and red). Provision of both a green and a yellow filter enables selection of either 520-570 nm OR 570-600 nm wavelength ranges from the broad spectral distribution generated by Lumencor’s proprietary luminescent light pipe source. Near-IR output is a purchase option requiring substitution of either the teal or red source.

Lumencor’s standard optical bandpass filters for the SPECTRA X light engine are listed below. For OEM customers, Lumencor can provide bandpass filters for SPECTRA X, SPECTRA and AURA light engines in addition to those in this list. For assistance with specifications for non-standard filters, please contact Our Lumencor sales team will be pleased to assist you with price quotations for non-standard filters. Typical power outputs from a 3 mm diameter liquid light guide for each standard filter installed in the appropriate position in a SPECTRA X light engine are listed in the table. Specific values measured in our test facility for each light engine before it is shipped are reported on the Certificate of Conformance issued to the customer. The table also provides links to downloadable text files containing transmission spectra for each filter. These data may imported into plotting programs for assessments of SPECTRA X output compatibility with dichroic beamsplitters and excitation spectra of fluorophores.

✦ Specimen measurement of SPECTRA X light engine output power through 3 mm liquid light guide. These values represent averages of measurements on multiple SPECTRA X light engines. Values for individual SPECTRA X light engines will vary. Specific power output values for individual SPECTRA X light engines are reported on the Certificate of Conformance issued to the customer.

‡ Filter not compatible with SPECTRA or SPECTRA X light engines.  Output power quoted for AURA light engine with 3 mm liquid light guide.
