Freeform optical device does a lot in a small packageIn a recent paper in Light: Science & Applications, University researchers Jannick Rolland and Jacob Reimers describe an optical device with potential applications ranging from improved satellite and diagnostic imagery to more precisely matching the paint color on a living room wall.
The device is a type of spectrometer—an optical instrument that takes light and breaks it down into components to reveal a catalogue of information about an object.
Unlike traditional spectrometers, however, this one is designed using freeform optics, a relatively recent advance that upends more than a century of optical design.
For more than 125 years, optical design was constrained to using rotationally symmetrical, often perfectly spherical surfaces placed in round tubes—for example, single-lens reflex cameras and microscope objective lenses. Each lens element in such a design can contribute up to 15 aberrations that limit field of view and resolution.
The advent of computer numerical control and new diamond turning technology has made it both feasible and economical to design and fabricate far more complicated, freeform optical surfaces that dispense with rotational symmetry. Freeform design enables a device to efficiently correct aberrations with fewer, smaller lenses and mirrors. The result, researchers say, will be sensors, mobile displays, and a host of other devices that are not only smaller in size, lighter in weight, and less expensive—but also out-perform those containing traditional lenses and mirrors.
Reimers, a PhD student and the lead author, and Rolland, the Brian J. Thompson Professor of Optical Engineering and Reimers’s thesis advisor, describe a spectrometer using three freeform surface mirrors, that:
- is five times more compact than similar spectrometer designs using more conventional mirrors;
- allows a three-fold increase in the bandwidths analyzed;
- and is 65 times more effective at correcting aberrations that affect field of view and resolution.
“Spectrometers monitor the environment, help examine patients, and are broadly used for many other applications. What we found here can be applied to spectrometers used in all of these other applications,” says Rolland. “That is the power of freeform optics.”

Experimental drug reverses obesity-related liver diseaseA drug developed at the Medical Center protected mice from one of the many ills of our cheeseburger and milkshake-laden Western diet – non-alcoholic fatty liver disease.
In a study in the journal JCI Insights, scientists report that a drug called “URMC-099” reversed liver inflammation, injury, and scarring in animals fed a diet high in fat, sugar, and cholesterol. The diet was designed to replicate the Western fast food diet and recreate the features of non-alcoholic fatty liver disease found in people. The drug was well tolerated and the research team plans further testing in order to move URMC-099 into early phase human trials.
Eating lots of fatty and sugary foods triggers inflammation in the liver and the body responds by sending immune cells to neutralize the threat. Unfortunately, the immune response can rage out of control, creating even more inflammation and further damaging the liver. URMC-099, which was discovered in the laboratory of Harris A. (Handy) Gelbard, dials back the immune response to a normal level.
“URMC-099 seems to break this vicious cycle of persistent inflammation by restoring balance between immune cells and liver cells,” said Gelbard, professor and director of the Center for Neurotherapeutics Discovery. “The drug’s ability to turn down the volume on the immune response allows the liver to regain its normal functions.”
A new therapy for non-alcoholic fatty liver disease is needed now more than ever. According to the Centers for Disease Control and Prevention, more than a third of adults in the U.S. are obese and that number is expected to climb.

PI oversight: Differentiating between routine care and research procedures(This is part of a monthly series to help principal investigators understand their role in ensuring that human subject protection requirements are met in their studies.)
A well-written, clear, and concise study protocol is key to the success of human subject research. As protocols increase in complexity, entwining research procedures and routine care/standard care procedures, maintaining research compliance becomes more of a challenge.
A first step in meeting this challenge is to clearly differentiate routine procedures versus those specific to the research in the study protocol. Key distinguishing factors include the intent of the procedure, when and how the procedure is conducted, and the ability to exercise judgment.
- The intent of a research procedure is to generate data in order to answer a question; the intent of a routine or standard of care procedure is to directly benefit an individual patient, client, or student, for example diagnosing or treating an individual’s disease.
- When and how research procedures are conducted are limited to the confines of the study protocol. Conversely, routine procedures are driven by patient/client/student need and/or professional standards, with freedom to exercise judgment within applicable policies/regulations/standards.
All study protocols including routine or standard care procedures must clearly delineate what procedures will be conducted per routine care versus those that are augmented for the purposes of the study (e.g. conducted more often than the standard). Protocols should also clarify if and when judgment, based on professional standards, can be exercised.
Environmental Health Sciences Center offers funding for pilot projectsThe Environmental Health Sciences Center (EHSC) has funds to support a limited number of pilot projects. The objective of a pilot project should be relevant to the theme of the EHSC: environmental agents as modulators of human disease and dysfunction. This includes research that investigates how the environment alters stem cells, how early-life exposures shape adult health and disease, and how the environment alters host-pathogen interactions.
Applicants may request a maximum of $30,000 for the duration of one year and must hold a tenure-track faculty position. Applications from new investigators collaborating with existing EHSC faculty are encouraged. Funds are restricted to research expenses and staff salaries, and cannot be used to support travel, faculty salary, or equipment purchases. Junior faculty may use a portion of these funds for salary support.
For more information, contact Michael O’Reilly or Pat Noonan-Sullivan, or go to the EHSC website.
The deadline for submitting initial applications is September 1.
Proposals must be submitted electronically by email to Patricia_Noonan@urmc.rochester.edu (Phone: x53265).
