Photonics West 2024 Recap<\/h4>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1709047235632{margin-bottom: 0px !important;}”]\n

We had a great time at Photonics West this year. People enjoyed the Yellowstone theme we presented with the Cowboy hat drawing. Many participants threw their business cards into the hat and one lucky person won the Stetson. He should be sporting it around Carlsbad, CA soon.<\/p>\n

There was a lot of interest in the newly advertised custom design services, and many were pleased to know that we are welcoming all types of product variations around our standard products. Andy and Dirk are busy following up with all the people from the show who had special requests. Cheers to another successful Wavelength Photonics West show!<\/p>\n[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”68617″ img_size=”full” alignment=”center”][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1507146836113{margin-top: 5px !important;background-color: #000000 !important;}”][vc_column width=”3\/4″][vc_empty_space height=”12px”][mk_fancy_title color=”#ffffff” size=”22″ force_font_size=”true” size_smallscreen=”20″ size_tablet=”18″ size_phone=”16″ txt_transform=”uppercase” margin_top=”10″ font_family=”none”]Subscribe to our newsletter for tips, techniques & product updates.[\/mk_fancy_title][\/vc_column][vc_column width=”1\/4″][mk_button dimension=”flat” corner_style=”rounded” size=”medium” url=”http:\/\/teamwavelength.us4.list-manage.com\/subscribe?u=e683bb028455c6da2682e79a6&id=cb59ea9375″ target=”_blank” align=”center” margin_top=”15″]Subscribe [\/mk_button][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”22px”][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_single_image image=”68619″ img_size=”full” alignment=”center” onclick=”custom_link” img_link_target=”_blank” link=”http:\/\/www.teamwavelength.com\/maintenance\/download\/applicationtechnotes\/cs-ld10.pdf”][vc_column_text css=”.vc_custom_1709047296332{margin-bottom: 0px !important;}”]\n

CASE STUDY: Quantification of the Removal and\u00a0Inactivation of Virus Particles<\/a><\/em><\/h4>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1709047422076{margin-bottom: 0px !important;}”]\n

Researchers from the Netherlands have developed and demonstrated a new method of quantifying and characterizing antiviral properties of polymer-functionalized surfaces for virus filtration and inactivation. Specifically, a polyethylenimine (PEI)-coated poly(ether sulfone) (PES) micro-filtration membrane was used to adsorb, inactivate, as well as disassemble virus capsids. Using fluorescence microscopy, spectroscopy, and single particle counting, only a small fraction (1%) of intact viruses can pass through the membrane, and a large fraction of viruses became inactivated and disassembled. Not only does the virus adsorb onto the PEI coating, it also interacts with PEI to disassemble the virus capsid. This new method provides a simpler and faster quantification and characterization technique for virus filtration and inactivation in the medical and biological world.<\/p>\n

In this single particle counting design with fluorescence microscopy, researchers benefited from Wavelength Electronics’ laser diode driver,\u00a0LD5CHA<\/a>, with worry-free setup and easy integration. The LD5CHA enabled precise current control of the laser diode with minimal electronic noise from the driver. As noise could contribute to any false positive readings, lower electrical noise may lead to better spectra recordings and data analysis. The peak fluorescence wavelength red- or blue-shifted by ~3 nm for intact or disassembled virus particles, and the laser driver ensured narrow linewidth from the laser diode for precise detection of the fluorescence spectra.<\/p>\n<\/div>\n

CASE STUDY: Determining Localized Density\u00a0of H2<\/sub>O2<\/sub>\u00a0Using Absorption\u00a0Spectroscopy in Plasma Jets<\/em><\/a><\/h4>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1709047521808{margin-bottom: 0px !important;}”]\n

Researchers from Germany have developed and demonstrated a new diagnostic technique for obtaining local distribution of gas phase hydrogen peroxide (H2<\/sub>O2<\/sub>) in plasma jets. Continuous-wave cavity ringdown spectroscopy, with a quantum cascade laser at a wavelength of 8.12 \u03bcm, is used to determine the effective absorption length of a cold atmospheric pressure plasma jet and to determine the localized density of H2<\/sub>O2<\/sub>\u00a0in the effluent of the plasma jet. With axial and radial scans and radial distributions, the effective absorption length was calculated to be 1.6 mm close to the nozzle and 5 mm at a distance of 10 mm from the nozzle. The maximum density of H2<\/sub>O2<\/sub>\u00a0was 2 \u02e3 1014<\/sup>\u00a0cm-3<\/sup>\u00a0in the center of the effluent close to the nozzle. This work shows the formation and consumption mechanisms of H2<\/sub>O2<\/sub>\u00a0and enables other biomedically relevant species in the plasma zone to be studied using this technique.<\/p>\n

Measuring the localized density of H2<\/sub>O2<\/sub>\u00a0with high-accuracy requires high precision and stable control of the quantum cascade laser when using continuous-wave cavity ringdown spectroscopy (cw-CRDS). Wavelength Electronics’\u00a0QCL1000 OEM<\/a>\u00a0driver enabled precise current control with minimal electronic noise from the QCL. As laser linewidth is a major concern for QCLs, the QCL1000 OEM minimizes noise for open air measurements to as low as 0.7 \u03bcA up to 100kHz as well as keeping the average current noise density to as low as 2 nA \/ \u221aHz.<\/p>\n

The stability of the QCL temperature is also critical for consistent wavelength output from the QCL. Wavelengths’\u00a0PTC5K-CH<\/a>\u00a0temperature controller, can precisely stabilize temperature to as low as 0.0012\u00baC.\u00a0The QCL1000 OEM QCL driver and PTC5K-CH temperature controller enabled the localized density detection of H2<\/sub>O2<\/sub>\u00a0using cw-CRDS.<\/p>\n<\/div>\n

Invitation from CEO, Mary Johnson<\/em><\/a><\/h4>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1709047786264{margin-bottom: 0px !important;}”]\n

From our home and factory in Bozeman, Montana, we are pleased to announce a new service offering: Custom Engineering.<\/p>\n

For over 30 years, we have researched best in class laser diode control circuitry.\u00a0 We started by bringing instrument level performance to OEM components, simplifying the design process for laser system engineers. Our off-the-shelf OEM laser diode and quantum cascade laser drivers and temperature controllers help with initial development and proof of concept where stable wavelength, power, current, or temperature are critical.\u00a0Our LAB instruments, with intuitive touchscreens, simplify research now.\u00a0 We\u2019ve come full circle.<\/p>\n

We complement our solid foundation of circuit knowledge and firmware\/software skills with high reliability electronics manufacturing.\u00a0 With a Return Rate consistently below 0.1%, we actively partner with our client\u2019s manufacturing teams, delivering on time and navigating all the electronics supply chain issues.<\/p>\n

Behind the scenes, we\u2019ve also successfully built many custom assemblies that exactly fit a client\u2019s need for form, fit, and function.\u00a0 Whether the need is for multiple channels, higher current, low noise, a different enclosure, (and much more!), we\u2019ve responded with specific solutions that accomplish the desired end results.\u00a0 We\u2019re now more widely announcing our capabilities and invite you to contact Andy Krause (andy@teamwavelength.com<\/a>) with any requests.<\/p>\n

I look forward to working more closely with you in 2024!<\/p>\n

Warm Regards,
\nMary<\/p>\n
