KEY FEATURES
Meadowlark Optics now offers Wide Field Retarders, the latest innovation in near zero-order polymer retarder technology. At their design wavelength, Wide Field Retarders provide a consistent retardance value over a wide acceptance angle, out to 30° or more.
Standard quarter- and half-wave designs are available for common wavelengths in the visible to near infrared region. The graphs show the Wide Field Retarder performance as a function of incidence angle for the both half-wave and quarter-wave designs.
Multilayer broadband antireflection (BBAR) coatings are included as standard. Note that BBAR coating performance varies with incidence angle; these coatings perform best at (or near) normal incidence.
As with all Meadowlark Optics retarders, the fast axis is conveniently marked. Custom retardance values are available for wavelengths from 400-1800 nm. Please call for application assistance or to request a custom quotation.

Cambridge, MA. From sculptedlight.org: Sculpted Light in the Brain is a recurring conference (founded in 2017) aimed at fostering collaborations between neuroscientists, computer scientists, optics researchers, and other scientists who share the common interest of using and developing novel technologies to observe and control neural activity in the awake, behaving brain. “Sculpted Light” refers to a broad class of methods where light is shaped to probe neural function. This meeting aims to promote future collaboration opportunities by gathering established scientists and the next generation of researchers from these fields to discuss future technologies that will enable real-time optical communication with the living brain.
