Welcome to NANEO

 

NANEO Precision IBS Coatings GmbH is a high-tech company specialised in the development and production of high quality optical coatings on substrates (lenses, crystals...)

NANEO's products are supplied to well-known customers in the laser and photonics industry worldwide.

OUR VISION

"THE MOST PRECISE OPTICAL COATER IN THE WORLD"

We develop and produce the most precise and demanding optical coatings in the world, and are both technology and market leaders in this field.

Our Products

We produce high quality optical coatings for applications in the fields of high power lasers, optical measurement systems, telecommunication, aerospace and for scientific research. NANEO gives you high precision hard coated optics with an enormous durability and environmental robustness.

Our production is mainly customer orientated and we only keep a small stock. For a better overview we have devided our products into different NANEO product groups.

We mainly produce industrial quantities, but with our flexible processing management we are also able to produce small quantities during the product development phase.

Dispersion Controlled Coatings

GVD / Group Velosity Dispersion Mirror
HDM / High Disperison Mirror
BSDC / Beam Splitter Dispersion Controlled

Our Dispersion Controlled Coatings comprise three groups:
Group Velocity Dispersion Mirrors (GVD), High Dispersion Mirrors (HDM) and Beam Splitter Dispersion Controlled Mirrors (BSDC). Dispersion controlled coatings are mirrors to compensate positive Group Velocity Dispersion (GVD) of all materials. GVD's up to several thousand fs² are possible. We can achieve these high values within tight tolerances.
The Dispersion Controlled Mirrors are fabricated with NANEO's proprietary precision coating technology in IBS (Ion Beam Sputtering) coating machines. Therefore NANEO achieves unique layer thickness precision. IBS provides the most dense, low loss, stable and durable optical coatings among the optical coating technologies.

Beam Combiner Coatings

BCW / Beam Combiner Wave Length
BCP / Beam Combiner Polarization

Beam Combiner Coatings are mirrors for combining two laser beams either by polarization or by wavelength. Steep edges enable dense wavelength coupling. High reflection and transmission values enable a minimum of beam power losses. Power transmission and reflection of several kW are possible. These requirements can only be realized with highly accurate measurement technique during the coating process and with a lot of experience in the design creation.
The Beam Combiners are fabricated with NANEO's proprietary precision coating technology in IBS (Ion Beam Sputtering) coating machines. Therefore NANEO achieves unique layer thickness precision. IBS provides the most dense, low loss, stable and durable optical coatings among the optical coating technologies

High quality optical ITO Coatings by IBS

ITO layer on a bare substrate
ITO layer embedded in high precision IBS optical coating

NANEO provides high optical quality high-transmission, low-resistance ITO coatings sputtered with the IBS technique either on a bare substrate or integrated in an optical coating. Substrates can be temperature-sensitive, as the sputtering process's working temperature is 100°C, and on demand it could even go down to 60°C. Typically achieved results (depending on ITO layer thickness) for a maximum transmission comprise a sheet resistance of 120 Ù/sq for an ITO layer thickness of 50 nm.

Laser Beam Splitter Coatings

BS / Beam Splitter
BSN / Neutral Beam Splitter
BSPP / Phase Polarization Controlled Beam Splitter
BSDC / Dispersion Controlled Beam Splitter

NANEO provides various types of laser beam splitters. The division ratio can be made polarization-insensitive e.g. Neutral Beam Splitters (BSN). The phase for both, s and p-polarization, is preserved by phase control in the Phase Polarization Controlled Beam Splitters (BSPP). The Dispersion Controlled Beam Splitters (BSDC) provides group velocity dispersion control.
The Beam Splitters are fabricated with NANEO's proprietary precision coating technology in IBS (Ion Beam Sputtering) coating machines. Therefore NANEO achieves unique layer thickness precision. IBS provides the most dense, low loss, stable and durable optical coatings among the optical coating technologies.

Gradient Mirror Coatings

GRM / Radial Gradient Mirror
GA (Gaussien), SG (Super Gaussian), BE (Bessel), PR (Parable)

The Radial Gradient Reflection Mirror Coating is a mirror with a reflectance that varies as a function of the radius. This mirror enables an optimal adaption of the beam profile to the application. A small and precise focus as well as a specified intensity profile are easily achievable. The wide range of the shapes of reflectance provide an additional degree of freedom in optical system design. Typical beam shapes are Gaussian (GA), Super Gaussian (SG), Bessel (BE) and Parable (PR) but customized designs are also available.
