Badges (on-site only)

On-site Conference attendees are reminded to wear their badge to access conference events. However, for safety reasons, please remember to remove your badge when you are outside of the FiO LS events and facilities. There will be a USD 25 reprint charge for any missing badge that needs to be replaced.

Conference Accessibility

The organizers of FiO LS embrace accessibility and full participation and are dedicated to providing ADA-compliant accommodations to people of all abilities.

FiO LS Management Staff will assist attendees with reasonable accessibility accommodations to ensure a full experience for all. In order to plan effectively, we respectfully ask that individuals needing accommodations provide our management staff with advance notice and pertinent information during the registration process. You may indicate your desire for a member of the FiO LS Staff to contact you directly to discuss your individual needs.

For on-site participants:

FiO LS Staff will continue to make every effort to accommodate reasonable requests we receive onsite. To easily locate accessibility services, look for the ADA symbol throughout the conference, on our website, and in attendee materials. In order to accommodate the environmental sensitivities of some of your peers, if at all possible, please consider that moderation and restraint in the use of perfume, cologne, or scented products in sessions and events greatly enhances the ability of individuals who suffer from chemical sensitivities to fully participate in the FiO LS program.

Event Cancellation

In the event that FiO LS is cancelled, Conference attendees will be returned the registration fee only. Any fees associated with cancellation of travel or housing reservations is the exclusive responsibility of Conference attendees.

Alcoholic Beverages (on-site only)

Recognizing the nature of receptions and the potential for alcohol abuse at conferences, all FiO LS sponsored events will make non-alcoholic drinks available. Conference participants are responsible for their own well-being and agree that neither FiO LS and/or its sponsors will be held accountable for any events or occurrences resulting from excessive drinking, recklessness or negligence.



Each contracted exhibitor can purchase Virtual Exhibitor Full Conference Passes at the rate of USD 200.00 to receive access to the technical portion of the conference. Registration for Virtual Exhibit Booth Staff is complimentary. Registration forms will be availble for download in the Exhibitor Service Center. 


Each contracted exhibitor is entitled to one complimentary technical badge and unlimited personnel badges per 10’x10’ or tabletop space rented. Access to the exhibit hall during set-up and tear-down hours as well as extended hours on exhibit days is permitted with these badges. If exhibit space is cancelled for any reason, all paid technical upgrade badges will be converted to full conference registrations, and all other badges may be cancelled or converted to Events + Exhibits Pass badges. It is the exhibitor’s responsibility to register their outside contractors for the appropriate badges. Each person who is registered as an exhibitor is responsible for picking up their own badge. Primary contacts are not automatically registered when signing up for their booth.

Force Majeure

The organizers and co-sponsors of the Conference shall not be held responsible for any delay or failure in performance of their obligations hereunder to the extent such delay or failure is caused by fire, flood, natural disaster, strike or labor dispute, military authority, imposition of law or regulation, riot or civil unrest, acts of God, acts of terrorism, acts of war, epidemics, pandemics, restrictions or recommendations issued by a governmental agency or recognized health organization such as the CDC or World Health Organization, the un-availability of the Venue or other similar exigent circumstance or emergency beyond the organizer’s and co-sponsors’ reasonable control, making it illegal, impossible, impracticable or inadvisable in organizer’s and co-sponsors’ sole discretion to hold the Event.  For one or more of such reasons, the organizers and any co-sponsors of the Conference may postpone, reschedule or cancel the event without liability on their part. In the event the conference cannot be held or is postponed pursuant to this section, the organizers and co-sponsors of the Conference shall not be liable to attendee for any direct, consequential or incidental damages, costs, or losses incurred, such as transportation costs, accommodations costs, or financial losses.

 Health and Safety Practices (on-site only)

FiO LS Management will implement the latest regulations, guidelines and health safety recommendations issued by federal, state and local governments, the CDC and the event venue to mitigate the risk of COVID-19 or any other infection during the in-person conference and exhibition.  FiO LS Management may, in its discretion, implement further health safety measures that it deems necessary and advisable. 

Identification at Registration (on-site only)

Attendees are asked to present a Photo ID at registration in order to collect registration materials and may only collect their own individual registration packet. This procedure is in place to protect registration materials from getting lost and to allow FiO LS to monitor accurate attendance. Registration materials will not be provided without a Photo ID. Furthermore, registrants agree not to allow any other individual to participate in their place either at the conference, during the registration process, or any other conference-related activity including acceptance of these terms of registration.

Laser Pointer Safety Information / Policy (on-site only)

FiO LS supplies tested and safety approved laser pointers for all conference meeting rooms and for short course rooms if instructors request one. For safety reasons, FiO LS requests that presenters use our provided laser pointers available in each meeting room.

If using your personal laser pointer:

  • Please have it tested at your facility to make sure it has <5 mW power output. Laser pointers in Class II and IIIa (<5 mW) are eye safe if power output is correct. Labeling may not be accurate so testing the device is important. Commercially available laser pointers may incorrectly label their wavelength and power output.
  • We require that you come to the Speaker Ready Room on-site and test your personal laser pointer on our power meter. If the pointer fails to maintain a safe power level, you will not be able to use the pointer at the conference.
  • Misuse of any laser pointer could lead to eye damage. In California, it is a criminal misdemeanor to shine a laser pointer at individuals "who perceive they are at risk." Anyone who uses a non-FiO LS supplied laser pointer shall be personally responsible for any injuries associated with their use of the device and shall indemnify FiO LS for any and all claims or liabilities associated therewith.

Limitation of Liability (on-site only)

When participating in FiO LS and all of its events, you shall bear all risk of injury, illness (including Covid 19 or other infection), death, property damage or other loss. You agree to release, hold harmless and forever discharge FiO LS, Optica (formerly The Optical Society), The American Physical Society (APS), and the officers, directors, employees, representatives, agents, successors and assigns of each organization from any and all damages, claims, demands, liabilities, and causes of action arising out of or relating in any way to your participation in FiO LS and all of its events, including but not limited to the use of the convention center and lodging facilities.


Media registration for FiO LS is offered on a limited basis and is reserved for editorial members of the working media and for analysts. All members of the media and analyst community must present proper identification onsite in order for media credentials to be issued.

Membership Verification (on-site only)
