From spectroscopy to quantum optics — precision components for the experiments that push the boundaries of science.
Research labs often work across multiple wavelength bands — from deep UV to mid-IR — within a single experimental setup. Optical components must either be broadband or precisely matched to specific wavelengths, and swapping between them shouldn't require realignment.
Research experiments frequently require non-standard specifications — unusual diameters, exotic materials, or performance parameters beyond catalog offerings. The ability to manufacture to custom specs with tight tolerances is essential.
Unlike production environments, research labs often need just 1-5 pieces of a custom optic — and they need them quickly to keep experiments on schedule. Minimum order quantities and long lead times are project killers.
Research requires full traceability and documentation. Interferometry reports, transmission curves, coating specifications, and material certificates are not optional — they're part of the experimental record.
Scientific experiments must be reproducible. Replacement optics must match the original specifications exactly — same material batch properties, same coating performance, same surface quality — months or years after the initial order.
350 nm – 2 μm
The workhorse of visible-light optics. Excellent optical quality, widely available, cost-effective. Ideal for general-purpose lab optics, beam steering, and imaging systems.
180 nm – 2.1 μm
Essential for UV spectroscopy, fluorescence systems, and laser experiments. High damage threshold, low autofluorescence, excellent transmission from DUV to NIR.
130 nm – 8 μm
Low dispersion material for UV-Vis-NIR applications. Used in spectroscopy, Raman systems, and multi-wavelength setups where chromatic aberration must be minimized.
0.5 μm – 20 μm
Standard material for CO2 laser experiments and mid-IR spectroscopy. Broadband IR transmission from visible to 20 μm.
150 nm – 5.5 μm
Extreme hardness and chemical resistance for harsh sample environments. Ideal for high-pressure cells, corrosive atmospheres, and applications requiring window durability.
Coating selection depends on wavelength, power level and application environment. Common options for this application:
Single and multi-band anti-reflection coatings for transmissive optics across UV, visible and IR wavelengths. Minimizes etaloning and reflection loss in precision experiments.
Broadband AR coatings spanning multiple octaves — essential for spectroscopy, broadband imaging and white-light interferometry applications.
Protected silver, protected gold and enhanced aluminum coatings for broadband beam steering and reference mirrors across VIS to IR wavelength ranges.
Application-specific coating designs for unusual wavelength combinations, polarization requirements or extreme performance specifications. Engineered to your exact requirements.
Research and laboratory optics serve a fundamentally different market than production optics. The requirements are driven not by volume or cost-per-unit, but by performance, flexibility, and the ability to support experiments that may never have been done before.
Consider spectroscopy — one of the most common applications in research optics. A Raman spectroscopy setup might require a laser line filter at 532 nm, a longpass edge filter at 550 nm, a focusing lens, a collection optic, and a dichroic beamsplitter — all within a spectral range where every nanometer of transmission matters. The optical components must be specified not just for their individual performance, but for how they work together as a system.
Material selection in research environments is driven by wavelength first, then by performance requirements. For visible-light experiments, BK7 is the default — it's cost-effective, widely understood, and optically excellent for most applications. When you move into the UV (below 350 nm), fused silica becomes necessary. Below 200 nm, you need CaF2 or MgF2. In the IR, the material landscape expands to include ZnSe, Ge, Si, and various specialty glasses — each with different transmission ranges, thermal properties, and handling requirements.
One of the most common challenges in research optics is the "one-off" nature of custom components. A physics lab designing a novel interferometer might need a beamsplitter with a very specific splitting ratio, or a prism with an unusual apex angle. These aren't catalog items — they require custom manufacturing with tight tolerances. And because research budgets are limited, the optics need to be affordable even at low quantities.
PhotonEdge supports research institutions with a flexible approach: no minimum order quantities, custom specifications to tight tolerances, full technical documentation with every order, and turnaround times that keep experiments on schedule. From a single custom optic to a recurring supply of standard components, we provide the same level of quality and technical support.
Typical requirements: broad wavelength coverage, tight tolerances, flexible quantity, fast prototype turnaround.
