Remember that the application and selection process for OITE and IC programs may differ, so read information specific to programs that interest you.

To be considered for a SIP position, you should reach out to NIH Principal Investigators (PIs) and direct them to your completed application.

The decision to come to the NIH as a summer intern is an important one.  These are full-time research positions, and it is not possible to take summer classes or tend to other responsibilities during work hours.

You may have noticed that the lenses of your camera or binoculars have a purplish tint to them when viewed at a glancing angle like the illustrations below. This is a result of optimizing the antireflection coating for the midrange wavelengths, the greens. More of the reflected light is in the red and blue extremes of the visible spectrum. Analyzed from the point of view of the CIE chromaticity diagram, combining red and blue puts you on the "line of purples". Even with the simpler Newton color circle, you can see that emphasizing red and blue will give you somethin akin to magenta.

This program is for college, graduate and professional students interested in exploring careers in research and healthcare. These are full-time research positions within one of the NIH Institutes and Centers (IC) in the NIH Intramural Research Program. Research groups are located on all NIH campuses, including the main campus in Bethesda, MD.

The SIP application is currently closed. You greatly increase your chances of getting a position by completing your application and reaching out to potential research groups by mid-January.

Summer interns work in a research groups directed by a Principal Investigator (PI). We offer research opportunities in the biomedical, behavioral, and social sciences with opportunities to explore basic, translational, and clinical research. Students interested in biology, engineering, epidemiology, psychology, mathematics, chemistry, pharmaceutical sciences, nursing, physics, computer science, bioinformatics, and other health-related fields are invited to apply. Summer interns may not work in administrative offices or outside of the NIH IRP.

Thin film anti-reflection coatings greatly reduce the light loss in multi-element lenses by making use of phase changes and the dependence of the reflectivity on index of refraction. A single quarter-wavelength coating of optimum index can eliminate reflection at one wavelength. Multi-layer coatings can reduce the loss over the visible spectrum.

Single layer antireflection coatings are generally calculated for a midrange wavelength like 550 nm (green). With the assumption of a coating thickness of a quarter wavelength in the medium, the reflection can be calculated by using the normal incidence reflection coefficients.

A single layer anti-reflection coating can be made non-reflective only at one wavelength, usually at the middle of the visible. Multiple layers are more effective over the entire visible spectrum.

Summer interns in these programs  have access to all resources of the broader SIP program and also participate in orientation, leadership, professional development,  and well-being programs as part of a cohort or  learning community. The curriculum of each cohort program is tailored to the educational needs of the group. The OITE provides funding and works with interns in these programs on an appropriate research group placement.  The OITE sponsors the following SIP cohort experiences:

The focal length is the distance between the focal plane and the lens's nodal point. ... calculation starts with the focal length to which you have set the lens.

The idea behind anti-reflection coatings is that the creation of a double interface by means of a thin film gives you two reflected waves. If these waves are out of phase, they partially or totally cancel. If the coating is a quarter wavelength thickness and the coating has an index of refraction less that the glass it is coating then the two reflections are 180 degrees out of phase.

We also sponsor a Graduate and Professional School Fair in July and Summer Poster Day in early August, where our interns share their research with the NIH community.

Research groups are located on several different NIH campuses, including the main campus in Bethesda, MD. Before you begin your application, we encourage you to learn more about:
