Fiber optic illumination systems - LED & Halogen-Deuterium - Up to 150W

HOLMARC has expanded its range of fiber optic illumination systems with high-power LED and Halogen-Deuterium light sources. Though designed for use as a stand-alone device, it can easily be mounted on a frame or in a rack using screws. Standard light guide adapter ensures compatibility with all fiber light guides. For efficient coupling, HOLMARC also offers light source with integrated focusing optics for other fiber diameters as well. It can be directly coupled to all spectra products. Deuterium lamp can also be incorporated in this housing for UV applications.

Fiber optic illumination systems - Xenon & Mercury Discharge Tube

This stand-alone illuminator consists of a mercury or xenon arc lamp, lamp housing, mirror and power supply in single enclosure. It is designed to be used with a fiber optic guide which transmits intense illumination to the monochromator, spectrometer and other instruments. The lamp’s cabinet accommodates a standard filter wheel which slides easily in and out of a slot in the light path. We also offer a variety of patchcords and collimating optics along with mounts.

Model : HO-SPA-LSMD-OF200

Mercury Discharge Tube Model - std

Model : HO-SPA-LSXe-OF200

Xe Arc Lamp Model - 150W

Cuvette holder

Our cuvette holders are for standard 10 mm path length cuvettes to work in UV-VIS-NIR ( ~200nm - 2μm ) spectral range. These holders have two terminals (Three terminal holders are also available) for fluorescence measurements and one slot for transmittance / absorbance measurements. The embedded collimating lenses are made from fused silica material.

Cuvette holder with fiber optic collimator unit

This fiber optics cuvette holder is designed to attach directly to light sources and can be coupled to spectrometers via optical fibers to create a small-footprint spectrophotometric system for fluorescence and absorbance experiments. The holder is suitable for UV-VIS-NIR (200-1100 nm) applications and holds 10 mm square curvettes. Filter can be directly attached to the system for transmittance / absorbance measurements.
