The Heliopan Bay 6 RG 715 (88A) Infrared Filter corresponds to a Wratten 88A filter is designed to help capture images of how a subject reflects or transmits infrared light.

Infrared light waves occupy the space in the electromagnetic spectrum behind visible light due to their longer wavelengths. Many surfaces and materials react to, or emit infrared light waves differently than visible light waves, which provide the potential for photographs of subjects or subject properties that are otherwise invisible to the human eye. Such images require an infrared-sensitive medium such as infrared film or a digital photographic sensor which may be more effective when used without the infrared-blocking filters that are frequently built over them.

Conventional light sources such as the sun, photographic strobes, or incandescent lighting may be used to provide infrared illumination. However, because infrared films or digital photographic sensors can be more sensitive to the relatively higher energy and shorter-wavelength visible light those sources also emit, the effects of infrared light can be otherwise obscured. The Heliopan Bay 6 RG 715 (88A) Infrared Filter makes it possible to capture images of how subjects are illuminated by infrared light by blocking near-infrared, visible, and ultraviolet light waves while allowing 90% of infrared light waves 715nm or greater into the lens it is mounted onto.

This filter is constructed from Schott glass for increased optical clarity and features a brass filter ring for durability and jamming prevention.

Q: 1. Can I use this Graid shuttle with M1 MacBook Pro?

A: The SanDisk G-RAID Shuttle 4 is compatible with macOS 10.15 and later and Windows 10.

Q: 2. Hey can it work with a hp z820 workstation.my workstation has a thunderbolt port?

A: I did have to download software from there site so if I were you I'd just go on there and make sure they have it available for windows. Other then that it performs great

Q: 3. There are two Thunderbolt inputs on the back, are both required to use in Raid5?

A: No... you only need 1 in order to run Raid 5.

Q: 4. What is the drive speed when configured to Raid 10?

A: The only speed figures provided for the SanDisk Professional 160TB G-RAID Shuttle 8 8-Bay RAID Array are for RAID 5, which provides speeds of up to 1690 MB/s (read) and 1490 MB/s (write).

Q: 5. What is the usable capacity on this 24 bay NAS?

A: The QNAP QNAP TDS-H2489FU-4314 does not come with any storage drives installed, so the storage capacity will depend on the quantity/capacity of drives the user installs, and which level of RAID is used. All levels of RAID consume different percentages of your storage pool to create parity.

Q: 6. Are these units compatible with Dell Alienware Thunderbolt 4 connections?

A: Thunderbolt is a standardized protocol, so the SanDisk Professional G-RAID Shuttle 4 will be compatible with any Thunderbolt 3 or Thunderbolt 4 connection.

Q: 7. What brand HDs are they using in this? Many don't disclose.

A: The SanDisk Professional 144TB G-RAID Shuttle 8 8-Bay Thunderbolt 3 RAID Array (8 x 18TB) uses WD Ultrastar 7200 RPM Enterprise-class hard drives.

Q: 8. How do I turn off the alarm sounding every time the RAID synchronizes?

A: The mute button is located on the far right of where the buttons are located. You can find it on page 10 in the manual:a href= http://static.bhphotovideo.com/lit_files/103819.pdf target= _blank http://static.bhphotovideo.com/lit_files/103819.pdf/a

Q: 9. When using RAID 10 (aka 1+0), what can be done with the fifth drive? I'm leaning towards two units; both RAID 10. First unit will be a main working unit and I'd like the fifth drive to be a hot-spare. Second unit will be my backup unit and I want the fifth drive to be available to copy certain critical files to (I'll then swap it out with a blank drive and take the filled drive to an offsite backup location). Over time, I'll keep trading the fifth drives when updating the offsite backup. Thank you. Side note: I've downloaded the various documentation from LaCie, but have not found any details on RAID 10 configurations.

A: Not certain that the hot spare can actively be used.While not invalid, using the second unit as backup seems very conservative. Also your backup unit should have more capacity than your primary to allow for file variations and history. You could use the 2nd version in Raid 0 configuration or use a simpler JBod enclosure.As for the offsite backup - a pair of simple Lacie Rugged drives that you alternate seem to be more cost effective and easier to handle.

Q: 10. Can a second computer connect and access files while the first computer is still connected and writing to the drive/s?

A: Only 1 computer may connect to the SanDisk Professional G-RAID Shuttle at a time.
