Indian Summer – Product – Update’s – Webinars – Product news
|With the school holidays behind us and the weather still in summer mode, we are ready for the 2nd half of the business year.
We have some nice events in front of us, where we can meet you!
Not going to one of these event and eager to discuss your photonic needs, let us know and we are happy to visit you in person.

Over the last year, we have been busy extending our custom optical coating services capacity. EKSMA Optics is well-known for its wide choice of standard laser optics, and we can offer an even wider range of custom optical coatings designed, deposited and tested in our advanced coating & metrology facilities.
LIDT Challenge 2023, This summer, we celebrated our success at the Laser Induced Damage Threshold Challenge, organized by HiLASE Centre! Our winning coating – AR @ 343 nm with LIDT of 0.6 J/cm2 measured at 1 ps, 1 kHz, AOI 0°, p-pol with a testing sport size of 1 mm. (!)

Iceblink – Super Continuum Laser
Iceblink is a supercontinuum fiber laser covering the 450-2300 nm spectral range with over 3W of average power and superior stability (<0.5% std. dev.). It is a very versatile white light source with a world of applications in the scientific and industrial sectors, including absorption/transmission measurements for material characterization, VIS, NIR and IR spectroscopy, single molecule spectroscopy and fluorescence excitation.
The spatial coherence and broad spectrum of Iceblink makes it a great alternative to a classic lamp, single-line lasers, LEDs and ASE sources.
The PixelCam 9 band SWIR camera utilizes the latest developments in high-performance SWIR (Short Wave Infrared) image sensors combined with Salvo’s patented ability to create pixelated filters to create a multispectral imaging system capable of discerning 9 distinct spectral ranges between 1000nm and 1700nm.
This opens the door to a wide range of applications where distinguishing the different SWIR “colors” enables the possibility to identify other subjects much more clearly, just as a color image in the visible spectrum does when compared to a monochrome one.
The use of the SWIR spectrum though has many advantages such as the ability to penetrate deeper into certain substances and even see right through them when a visible image would be occluded or even completely opaque.

High Resolution Spectrometers
We are excited to introduce our latest innovation, the SynIRgy system, a groundbreaking advancement in the preclinical imaging field that is set to revolutionize the way we visualize and study tumors.
Key Features of SynIRgy:
See below a comparison of our three IR Vivo systems:
The SynIRgy system is the perfect combination of the power of bioluminescence and the advantages of NIR-II , making it an indispensable tool for researchers and clinicians working in the preclinical field.
All Optical Interference Bandpass Filters exhibit some degree of shift with the angle of incidence (AOI).
Since the layers of a bandpass filter operate in the coherence range of the desired wavelengths, a departure of AOI from zero degrees results in the shortening of the center wavelength. To achieve the desired bandwidth, standard optical bandpass filters are designed with the minimum layer thicknesses needed in the absentee spacer layers.
An example is given below (Fig. 1) of a standard bandpass filter centered at 750 nm with a bandwidth of 20 nm. One can see that the filter will still transmit the center wavelength (CWL) to a tilt of 15° AOI. This limits the function of the filter to about f/1.9 or a 30° full cone angle.
Fortunately, optical design strategies exist to reduce the angle shift, thereby increasing operating cone angle. These involve increasing the thickness of the absentee layers and consequently the number of cavity elements needed to maintain edge steepness.
However, this design is more complex and the deposition process is more difficult to control (and is more costly). Therefore, it is not routinely used in manufacturing, although, it is available as a custom filter option.
Mid Spatial Frequencies in Optical Surfaces Based on Interferometric Measurements
Modern optical polishing introduces mid-spatial frequency errors. Few standards exist to specify and measure mid-spatial frequencies. We propose Fizeau interferometry’s application characterized by power spectral density due to its flexibility and easy physical interpretation.
We look forward to supply you with all the information and material you need and answer any question.
