Phase masks for 800 nm fs inscription

 

Ibsen has introduced a new Phase mask product. We are pleased to present that we have developed a technology that allows for the 0. order suppression of Phase masks optimized for 800 nm TE illumination. With 1000-1100 nm period Phase masks, this has not previously been possible.

The development project included a trial production lot of a sample Phase mask of this type, with the following specs:

Engineering Sample Phase mask specifications:

A limited number of this Phase mask is available for immediate ...

How to Obtain a Large Absorbance Range

 

Absorbance spectroscopy is a molecular spectroscopy method that uses the wavelength dependent absorption characteristics of materials to identify and quantify specific substances.

Many molecules absorb ultraviolet or visible light emitted from a broadband light source. The absorbance is related to the concentration of the materials in the sample such that stronger absorbance means higher concentration.

Absorption Spectroscopy

There are many different approaches for measuring absorption spectra. ...

Don’t Waste Photons in Your Raman System!

 

In this post, we are focusing on your Raman system, by looking further into Raman spectroscopy, which is a molecular spectroscopic technique providing information about molecular vibrations that can be used for sample identification and quantitation.

Raman spectroscopy has some very unique advantages and is used in many different fields where a non-destructive, microscopic, chemical analysis and imaging is required. This is especially ideal for the pharmaceutical industry where this technique is used for incoming raw material inspection as well as ...

Focus on UV detectors for HPLC

 

Detectors for HPLC is the focus of this post, where we will get around HPLC and our FREEDOM UV-VIS spectrometer, which is a suitable UV detector for HPLC.

We often hear that instrument manufacturers are constantly faced with the challenge to develop new instruments that offer the end-user:

 

At Ibsen we believe that we can help solve some of these issues – if not all of them, with detectors for HPLC, e.g our FREEDOM UV-VIS. But first, what is HPLC?

High Pressure Liquid ...

Make or buy your spectrometer

 

One of the challenges instrument makers face today is an increasing need to bring new innovative products to the market faster and at lower cost. Spectrometers are an essential component in analytical instruments for a broad range of applications, for instance the life sciences, pharma, and process industries. Spectrometers are opto-mechanical modules that require specialized knowledge and equipment to design and manufacture. For many instrument companies it is not obvious which strategy – make or buy– they should choose ...

Multichannel Interrogator for FBG sensing

 

Fiber Bragg gratings (FBGs) have become more and more attractive in recent years because they are small, cost effective, easy to manufacture and insensitive to electro-magnetic interference.

The basic principle of FBG sensing is to measure the reflected spectrum and to track the FBG peak positions.

Due to the availability of low-cost tele-communications equipment, the most common and commercially available FBGs work in the ...

Developing high resolution OCT systems to diagnose glaucoma

 

Ibsen Photonics is participating in a newly started EU Horizon 2020 project, GALAHAD, aimed at developing high resolution OCT for glaucoma diagnosis. GALAHAD stands for Glaucoma-Advanced, Label-Free High Resolution Automated OCT Diagnosis, and the project was initiated in December 2016.

Glaucoma is a complicated disease in which damage to the eye’s optic nerve leads to progressive, irreversible vision loss. It is the second largest cause of blindness. It is not possible to cure glaucoma or restore lost vision, but disease progress ...
